Let’s talk about gun fight first, I think mabye you can find some cover objects to let you avoiding bullet in a gun fight, to covering you self, you can simple just walk behind some objects and press a “cover” button, you can also shooting while peek around corners, and I think mabye player may also can make a “quick avoiding” system, so you can use one key to let you characters dive through the air on any direction in a short time to avoiding some grenade blast or even a 40mm?(Just a idea, I don’t think normal people can really dodge a incomeing rocket or grenade launcher"but you will falling on the ground on a sec and take some time to stand up, you can also use it to move quickly on some place like you open a door, and turret just behind it, you could just dive through the door, and avoing to get shot, and cross that place safely,
and about parasitic, I think you may make more insect can parasitic the player, and can even cause mutation, and next, more mutation power?
last, I think mabye the characters need to learning how to put off the fire on them self, I think mabye you can just “stop drop and roll” to put off fire, but will take some time, I mean, you can do this on real life, so why not this game?
and end, I don’t know just me or other version, it seem the NPC characters a immune some effect, I mean, they can even walk over the lava and don’t take any damage, and can even go through the flame or acid without hurting themself, and why the zombie special attack a only work on player? can’t they just spit acid or shoot electricity at NPC?
In future version can you just recover the bulding’s power by connection wire between you vehicle?
