Unlike the previous shooter, Resident Evil: Operation Raccoon City, Umbrella Corps focuses much more on close-quarters battle (CQB) and tactical combat. Unlike previous installments, due to the focus on tactical combat players can aim their guns while on ladders, opening doors and while using their tactical shield.
Four special weapons have been identified so far:
The "Debrainer" or "Cronus", known only as the "Zombie Vile" (ゾンビバイル,Zonbibairu?) in Japan: a modified ice ax intended for destroying the link between the cerebrum and spinal cord.
The "Tactical Shield", known as the "Bite Guard" (ベイトガード,Beitogādo?) in Japan: an armored attachment to the arm which deflects bullets. It contains a sticky resin which can prevent zombies getting any closer should they get stuck.
The "Terrain Spikes", known as the "Zombie Climbing Irons" (ゾンビアイゼン,Zonbiaizen?) in Japan: these studded boots are used to destroy the heads of crawling and downed zombies to prevent any further attacks.
The "Zombie Jammer" (ゾンビジャマー,Zonbijamā?): a device which emits electromagnetic radiation designed to disorient nearby zombies, thus preventing the user from being attacked. The official website recommends destroying an enemy's jammer to prevent them escaping.
Being a multiplayer-based game, Umbrella Corps has more range in online gametypes than offline. "One Life Match" is a multiplayer mode where players fight during a three-minute round with only one life - if they die, the game is over. Another mode was added in called "4 Survivors", whereas 4 players would have to stay alive as long as possible while fending off enemies, whether they are the other player trying to survive or the countless zombies in the map. The game also features a single player challenge mode, titled "The Experiment", where the player goes through up to twenty trials. In one mission, the player is to kill a number of Zombies and obtain blood samples from their bodies. Another mission would have you defending an area for a set amount of time, and has to be repeated for several parts of the map.
