survival games

i heard survival and here i am with Dangan Ronpa
i wouldnt really call it a "game", but it's a game in a few of the character's eyes, and the winner lives

some of these may not be typical survival games but they do share aspects with them.

-fate/zero (amazing, maybe not exactly a survival game but a fight to the death) -pictured-
-deadman wonderland (only read the জাপানি কমিকস মাঙ্গা but it might ne what you're looking for)
-eden of the east ( a game to save the world, with cell phones! kinda like mirai nikki but wkthout the gore)
-sabagebu! (aka Survival Game Club. this is a comedy, don't expect to take this one seriously!!)
