Rivals are buffed but what if they had personality!?
Let me explain
What if they hunted you indirectly within a range of them.
Depending on machine type and level they would progressively addopt strang behaviors or tactics.
For example; keeping distance, charging at a moments notice, maybe a tank rival will lunge a short distance, a runner/hunter always taking the high ground or possibly running and gunning, harvester standing on hind legs for a grans slam, Harvester calling in reinforcements too land behind you, Dodging incoming fire instead of staggering, never standing still… machines light might not change color for trickery or mimick the sounds of other machines… I could see Apocalypse class rivals doing this😂
And then cosmetics, like battle damage or barbed wire wrapped around legs an hanging debris, parts of bushes, burns and draped cloth from tents.
Also unique sounds for effect
I want Rivals to be crazy, because its such a half hatched idea that much could be done with it.
