Gearbox Software has taken steps to make its awful game slightly less awful. The studio's second update for Aliens: Colonial Marines is rolling out on Xbox 360 right now.
The update covers issues and bugs found throughout both the campaign and versus modes. Notable fixes include letting co-op players revive their partners, and preventing players from walking outside the map.
Most of the issues addressed thus far seem to be relatively standard in terms of post-release support. PlayStation 3 and PC will also get the update, but Gearbox hasn't said exactly when it will be made available on those platforms.
