Hive Jump
"Hive Jump is one part Spelunky, one part XCOM, and one part alien ass-kicking. You and your friends take on the role of JUMPERS and make your way through underground alien hives in 2D platforming action. Kill aliens, dodge traps, gather resources and defeat the hive queen lurking at the bottom of the hive to complete the JUMP."
