the best thing would be that in the third RAZE in costume mach could choose their allys and enemies... and about multiplayer! There could be ranks, and in each rank a new super weapon, like that super weapon in Raze 2 which is allowed to use only in one level...
Have upgrades for weapons like silencer,accuracy,shoots fire and bayonet. and have perks like Juggernaut,second chance,radar and 20 seconds of invincibility.
For future reference, I think that a possibility of having full custom character would add character to the game, pardon the pun. choose race, armor selections that are interchangeable, and even classes such as grenadier, sharpshooter, etc.
raze 3 should also have vehicles[b]it would b good to have vehicles but it might wreck the game, people just bloody driving cars and**** LOL i like the idea of multiplayer, though
