Zombi U: Survival Mode Will Grant You Only One Life
Normally the game will put you in the shoes of a different survivor once you die. This however, will not be possible in the Survival mode as you will have only one life. There will be no respawns or second chances.
Additionally players can leave behind hints and helpful messages for other players, similar to what we had in Dark Souls. The messages can be read by the Wii U tablet by pointing it on surfaces in the game. Players coming to such messages will have to decide whether its legit or the one who left it behind is just trolling us.
