:IS2:
I was just thinking what would I do with KF if I were to update it or to take part in creation of KF2. I'll make it quick.
Game modes and difficulties:
Another way to make game more difficult: players hurt each other with all weapons, can see eachother's nickname's and lifebars. As an official game diffculty.
Also, campaign mode as an official one, with official campaigns and full support for this mode.
Weapons:
Allows players to sell, drop 9mm and knife.
Allow them to be a freakin badass only using their friggin fists. Also, dual machetes.
Add a melee attack to the most of weapons for the purpose of shoving of the pesky ones, not to deal the tons of damage.(except for the huge weapons which weight a lot, they should do some reasonable damage if hit with).
Gameplay:
"Tactical dismemberment". Make the point of shooting matter. Shooting the head causes more damage, shooting the leg causes less damage but slows zed down, shooting the leg off causes zed to fall down and crawl to the prey instead of walking. Same with the other organs. Also, make some critical points other that head for some of zeds, example: FP and his chest cylinder.
Also, make some new zeds and improve old ones.
