I saw this video a while ago and was tempted to upload it but I pussied out.
The game isn't actually a Unreal tournament mod, according to the internet its "forked" from a free game called Nexuiz which is Quake 1 source code based. The author was featured on a ED article because she is batshit insane. Please don't ask me why I bothered to dig up this shit in the past.

What? No linux download or git access? :o(
I still am working on digesting this idea of yours. Eating your opponent seems kinda gross to me, but I also turn the gibs off in Xonotic/Nexuiz so never mind me :oP
I think I need to register as a new user to this forum so I can give you another positive reputation, just for the idea of making real something totally crazy. I am baffled.
Edit: hmmmmm the "eating each other" part seems to be emphasized in a ...weird way and also a bit too much for me to still have the comical effect :o/ I think this fork is weirder than I can take it. Congratulations!"
So. Who wants to tell him? Keeping in mind that he might be entirely capable of shutting the project down if he finds out. PoE Red had the Prime Directive for a reason, after all.
