Very large above ground facilities other than warehouses. Public buildings, schools, Postal service, hospitals, police stations, convenient stores, Aldi or whatnot. More three plus story buildings. Such as grain elevators and drive in movie theater screen buildings.
Put interiors inside all the shops and stores that we have already.
Maybe reach out to the community and provide them with a tool that can allow them to design interiors of buildings using existing game assets. Not engine access, but maybe a tool to assist with the work load. (See Fallout 4)
Better quality/larger loot chests and lower the amount of lootable boxes/ Chests. Make finding a loot chest more meaningful by making them rarer with a lot more stuff in them.
Its super tedious looking in every car/house/barn/garage in order to find basic stuff. The Chests should have all weaponry, attachments, Ammo. Everything else should be in the environment.
For Example: Homes, (Bathrooms have med kits, adrenaline, and hairpins) (Garage, Car Batteries, Propane tanks, fireworks, etc…) (Cars, Should have car batteries and flares.)(Hospitals: Better health packs and team health boxes.)(Military bases, Ammo Boxes and higher quality Ammo Field Radios.)
Add a way to utilize the dead robots to create, armor or better yet cybernetic enhancements to your character.
Crafting remote triggered/crafted traps. For example: Boom Box, Garage Door opener and Craft that together and allow the player to use the Garage Door opener to trigger the trap. The player can then put the gas tanks/mines/whatnot down trigger the lure from range and shoot the traps when needed.
I would like the ranges on all the weapons increased substantially. The Rifles should be accurate up to 750 meters. The BMG round rifles should be accurate up to a kilometer or more. Right now it seems 400 meters is maximum for bullet travel. It does not seem very realistic.
Create AP rounds or HEAT rounds that actually can penetrate armor. Right now it just seems like that these rounds dont matter because if you are not hitting one of the designated weak spots on the bot, the AP rounds are pretty much worthless.
Real limb damage to the bots, Blowing off arms and legs to slow or stop them. Shooting joints and hoses should mess with the bots mobility.
