Not some bad ideas i like the one with different form but it would be a bit hard and i think a bit non halo to be a tiny flood or the stalker or ranger, the brute yeah but the problem is u would need to keep the main, body shape (spartan/elite) then have difference forms for that, like a runner, really fast but takes 3 hits to kill someone, a spawned, this could be what we become on or first death it runs like a normal spartan and has the gun the player died with and lastly the bruiser, moves at 50% speed 100% when sprinting and kills anyone with a 1 hit ko, 2 for an over shield obviously There my ideas on that but i still think the should bring back infection it was awesome
