Hi !
I have some suggestions for items of all sorts and perks. I’ll update this message with new ideas 
Useful clothes:
-Tactical glasses: It could be equiped on face or helmet. You could use the 3 different modes like with the weapons modes: night, xray or thermal. This way you’re not forced to aim with weapon to see like that. It would be great to be able to equip it with the gas mask too.
-Azmat clothes: Helmet, Shirt, Pants, Boots and Gloves. If fully equipped, it would protect us from any chemical or gaz damage.
-Riot Shield: To protect yourself from ennemies, could be in the left hand while holding weapons.
-Jetpack: to jump a lot higher and fly for a short time
-Backpack: Different backpacks that allow to carry more weight.
-Exo-armor like the Phenix one but that give more bonus (weight carrying, jumping as Hunter, charging like runners…). Or an update to the actual Phenix Armor.
-Utility belts: Some belts to equip and attach pistols and other items. Or simply to add bonus like more weight carrying, faster reload, faster weapon swap or faster items use.
-Camo Clothes like the sniper Clothes that makes you look like a bushes,increasing stealth.
Only-cosmetic clothes: (could be DLC)
-Police uniform: It would be legit to get it as there are many police car.
-Terminator look: Clothes inspired by the terminator franchise. The best part would be face make-up with red eyes and half the face show a metal skull… Would be an epic style to fight robots !
-Viking armor: A funny way to explore this nordic area… A viking helmet, beard and armored clothes with some fur. Would perfectly fit with the electric KVM for a modern day son of Odin !
-Predator-like armor: A huge metal helmet with dreadlocks and a futuristic/tribal armor. Inspired by the predator franchise.
-Space Troopers: A white armor inspired by the clone/stormtroopers of star wars
-Metal Armor: An Iron Man-style Armor to fight our Iron enemies !
-Astronaut clothes: would be nice with a Space-style dlc
-Super hero costume: with a cap and a mask, to have a badass or funny look. Different colors for it.
-Professor Clothes: Some clothes inspired by Doctor Who.
-Detective clothes: To look like Sherlock holmes
-Rangers clothes: Clothes inspired by the power Rangers, with different colors.
-Survivor clothes: Clothes inspired by Ranbow the soldier.
Utility:
-Motion Detector: A tool that detect movement. We could collect it on machines and it would replace the furtivity help. You could use it to hunt machines and detect them at bigger range. We could carry it in our left hand while holding a pistol or it could be equipped as a watch. You could select a specific type of enemy to detect. It could show how many machines are around, in which direction and maybe wich model it is… Better quality of tool, better range ! It’s inspired from the Alien Motion detector in the Alien franchise. It would be useful. You’re walking and then you hear the device starting to “bip” more and more… It would be fun !
-Flashlight A change to the actual way it works. Right now it looks like the light come from nowhere… Having different lights to hold in the hand or attach to shirts, helmets and Weapons. With different qualities that change the range/power of the light, and the stealth of the character.
-Hacking computer/device: It allows to hack and control machines. It should work better with the associated perk
-Bear trap to slow/stun enemies
-Radio blocker: You can place it in an area and it will Block the ability of harvesters in the area to call supports.
-Harvester emettor: You collect it on harvester. You can place it somewhere and it will spawn hunters around as long as not destroyed.
-Gasoline tank: you can open the tank and put gasoline tracks on the floor. Shoot it and the track will burn. It would be perfect to trap enemies.
Explosives:
-Plastic explosives: You can place them on the ground, walls or machines and make it explodes with a radiocommand.
-Inflammable gaz tank: A new gaz tank or an upgrade to the actual ones. You quietly open the tank and the gaz get out, making a cloud like the smoke grenade around. But when you shoot the cloud it will burn/explode! If not shot, the cloud will disappear after à while. This way it could be more spectacular and funny to explode!
Weapons:
-Grenade Launcher to shoot grenades. As ammo it could use the different classic grenades. It allows a more accurate and a longer distance shoot ! The Experimental could shoot the same grenades as the apocalypse tank explosives Mine.
-Sword: We need melee weapons to fight the robots ! With the aim control you could protect yourself from the Hunter blade too. You could get it this blade by killing Hunters! The experimental could have a laser blade.
-Flamethrowers: The robots have it and it’s OP. So we should get it on their corpses for a more egal fight ! Let’s melt some bots ! The experimental could freeze enemies instead of burning them.
-Crossbow: To shoot craftable arrows. You can have normal arrows, flare arrows, firework arrows, EMP arrows, explosives arrows, remote-explosives arrows and a tracking arrow that highlights the enemy as long as it’s not destroyed, making it easier to follow. A cable arrow would be fun to use, you could attach bots together or attach them to wall or ground to stop them from moving, totally changing the way to fight them. You could use the cable arrow to climb buildings too. The experimental crossbow could automaticly reload.
-Minigun: It slows the character but is extremely powerful. The experimental could shoot laser bullet.
-Experimental Squovist that shoot flares ammo, highlighting enemies
-Experimental AG5 with acid bullets that inflicts damages to armored plates.
-Experimental AL with electromagnetic bullets that slows the target movement speed.
-Experimental Altgstudare with auto-targeting system: once activated it locks the view on the target and follow it automaticly.
-Experimental Meusser: Low speed stealth ammo that deal damages to machines without them detecting it.
Experimental HP: The bullet bounces on enemies and surfaces many times.
Experimental KVM 89: The more you shoot without stopping, the more accurate it becomes.
-Experimental Moller: Tracking-ammo, the bullets will automaticly aimed towards enemy.
-Experimental Magnus: Russian roulette-style, one ammo per reload is randomly explosive.
-Bowling ball with explosives inside. You throw it and it explodes, would be a funny weapon.
-Molotov cocktail to put the bots on fire
Weapons attachments:
-Motion detector: As the utility tool described sooner but this time it could be attached to Weapons and we could see it while holding the weapon without aiming.
-Bipod for rifles and machine Guns ! While lying down or aiming from the border of à Windows, you could shoot while aiming easier !
-Laser: to help targeting ennemies at short range. It could also highlights the Target to help the teamates to aim at it.
-Different skins for Weapons as different camouflage and colors.
-New heat-tracking ammo for the rocket launcher.
-Grenade-launcher attachment for assaut rifles.
-Bayonnet attachment to Weapons.
Perks, abilities and others:
-We should be able to swim in lakes and rivers, using stamina.
-We should be able to lie down on the ground ! Being more stealth but moving slower.
-Being able to glide while running and then crouching.
-Having a melee attack when holding a weapon to hit ennemies that are too close.
-Being able to climb on things with a double jump: Helping to get on top of building or trucks for exemple. We could also get climbing picks to reach the top of big buildings and mountains !
-Ability to build construction as barricades (like the one around the Himjfall hotel)
-Ability to upgrade safehouses: Adding defensives things as wooden plates on windows, mounted weaponry, alarm detectors, camouflage or hacked bots that will protect the safehouse.
-More destroyable things like: trees, walls, doors.
-More damaged-specific behaviour to machines: If we destroy their captors, they can’t see us. If we destroy their legs they can’t move anymore… Explosions break them in multiple parts, fire make them melt.
-New tracking IA: the machine Detect players independantly. They will attack one without always detecting his teamates. When you’re in a building they watch the doors and Windows but they don’t EXACTLY know where you are unless they have a visual on you.
-Special Harvester convoy: Like the Rival system, there could be special Harvesters with specific rewards when killed. Those ones will try to flee from you and will be heavily escortes. But they give a lot more ressources than others.
-Weather conditions and machines: Fog should make you stealthier, rain should make EMP more powerful, lighting should strike machines sometimes with the same effects as EMP.
-Double Weapons holding: You can use two pistols or two Light machine guns at the same time.
-It would be nice to see the equipped weapons on our characters: Both main weapons could be attached in the back, the pistols could be attached to the belt.
Vehicles:
-Car, there are so many so it would be great to be able to drive one.
-Trucks, there are some of them and it could be fun in coop or to block the way to tanks and harvesters.
-Armored tanks: There are some, both destroyed or unused. Could be epic to use but it may attract machines because of the noise, especially tank machines.
-Aircraft: Like the tank, there are some of them and it would be good to use. But it would be targeted by harvester and tanks. Maybe the robots would shoot tick pods to it and the tick would dissassemble the aircraft while it flies (like the droids that attack the jedi starfighter in Star Wars III)
-Boats: Small boats could be fun.
-Motorbikes to move fast everywhere
New regions:
It would be good to have more areas to explore. Other Islands around the mainland could offer some opportunities. Another idea, looking at the retro scifi style of the game, could be to use “teleporting portal”, StarGate or Stranger Things-style. It would fit the style and bring a whole new dimensions to the scifi in the game. The teleporting portal could transport us to other country, continents, planets (like the moon) and maybe other time period or dimensions. This way we could get a lot more diversities in places and context to fight the robots ! It could be huge new maps or just some small islands, valley lost in mountains (all roads blocked by rocks) and other possibilities… It would refresh the way we play the game with totally different context. Robots could use the portal to try invading other places ! Or it could be the result of other country experiments too.
-Tropical map: More trees and bushes. Maybe some natural fauna ? Less building so you’ll need more furtivity. We could have more sun too, wich would change a lot the ambiance. It could be inspired from the Amazonia in Brazil or Bolivia… Or in Asia too. Imagine being lost in the jungle and hearing the robots without seeing them because of the trees !
-Desertic map: Less places to hide, it would be perfect to introduce vehicles like a jeep. Could be inspired by north african countries. A great context for battles with more fire power!
-City map: Fighting robots in a big city (Stockholm, Berlin, London, New York…). Could happen after a global invasion by the robots… Seeing famous monuments would be cool and fighting robots in big building or mall would be fun ! It could also be a “fake city” to avoid the “observe & copy” work of recreating a real place. It would be a good place to introduce a better AI for runners that could explore buildings and rooms. You could enter cinemas, bowlings, museum, huge retro mall, warehouse and stadiums. And fight robots in those funny places !
-Cruise/Military ship:
Fighting robots on a huge ship could be cool: Through the machines rooms to the Command room it could be fun ! This place would be smaller than other map so can be a part of another map or even added to the crurent one (maybe a rescue ship attacked by the robots, both a Titanic-like huge ship or an Aircraft ship.)
-Submarine base: A secret Submarine base of the Swedish army, it could be hidden in the sea around the actual map and would work as a huge bunker.
-Space map: It sounds crazy but what about fighting the robots on the moon ? If Sweden has robots, maybe another country (Russia, USA…) has an hidden base on the moon and the robots tried to invade it. A funny place to fight and when you get out of the station, you move with lower gravity ! It would be epic !
-Medieval map: A map with castle and old houses… Could be a new small map or the actual map but with different buildings/places ! The actual ruins that we see in the classic map could be replaced by full castle. A little time-travelling version of the game that could be fun. Maybe with knights/vikings clothes and weapons too.
-Futuristic map: A new small map or a new version of the actual map: With more robots and futuristic building made by the robots. It would be fun to see how the map will change since the robots invasion.
New bots:
-A robot with wheels that could spawn mines on the ground. It would carry a lot of explosives but it’s heavily armored. You should take care while biking, if you roll on a Mine…
-an engineer bots that collect pieces of destroyed machine. It can spawn a lot of ticks and heals other bots. Kill it to get a lot of machines components.
-a bulldozer-like bots that can destroy barricades, doors and maybe walls.
-Artillery bots: an Heavy and slow bot with a huge canon. It shoot from far away without even seeing you. It shoots where the flying drone sentinels communicate to shoot.
