Capcom shared the "Night Treasures" mission from E.X. Troopers, a Lost Planet spinoff that plays like Monster Hunter with guns. Bren can collect items after activating data points and defeating Akrid like Dongo. If you played Lost Planet you may recall Dongo, which has the same rolling up into a ball attack pattern in E.X. Troopers.
E.X. Troopers comes out on November 22 for Nintendo 3DS and PlayStation 3.
