Call of Duty: Modern Warfare 3's Zombies mode has been trapping some players inside of Mimics, one of the game's larger and more challenging enemies roaming Urzikstan. Having launched earlier in November, Call of Duty: Modern Warfare 3 was released to mixed reviews, as many felt the length and quality of the campaign was subpar, and the new DMZ-inspired open world Zombies mode has alienated fans of classic round-based Zombies. That said, the game's multiplayer component has received some praise for its 16 remade Modern Warfare 2 (2009) maps and much improved movement.
