Zombiecraft
Zombiecraft is a Minecraft server that offers a unique zombie apocalypse survival experience. If you like zombies, you're at the right place. The game can be played with up to four players co-op fighting against waves of zombies. During your survival, you'll be able to unlock new parts of the map to explore and find better gear from mystery boxes, perk machines and wall weapons scattered around the map. Make sure to protect yourself and your comrades by keeping barricades up to slow down zombies. Survive as long as you can before the zombies catch you. Oh! And did I mention this is a vanilla-compatible minecraft server? That's right, Zombiecraft requires no-mods to play, just hop in and you're ready to kill some zombies.
