Indie developer Emotional Robots has released what it calls a "massive update" for its Unreal-powered iOS multiplayer first-person shooter Warm Gun.

While the game's initial release in October was criticized for its technical hiccups, the latest update focuses on stability and bugfixes. The game now includes a new map, a kill/death ratio, and "improved control schemes, AI, UI, and registering/logging processes for smoother online gameplay."

Emotional Robots also notes that cross-platform performance has been boosted by roughly 40 percent, which should be good news for anyone experiencing difficulties with earlier versions.

Warm Gun is on sale for $1.99 until the end of February.
