Epic Games today announced that they are partnering with several indie developers to bring the Unreal Indie Bundle to Steam. The pack is made up of seven games that utilise the Unreal 3 Engine, all for the price of 20 dollars.

Sanctum and Dungeon Defenders are two tower defense games with a premises that seems to have become more popular in recent years: the player not only places towers but also fights alongside their structures. Both gamers also feature co-op gameplay with up to four other players. However it’s there that the comparison ends, as Sanctum opts for futuristic, shooter style combat while Dungeon Defenders has more in common with a fantasy RPG.

Q.U.B.E. and Unmechanical are both puzzle games, but with markedly different approaches to the genre. Q.U.B.E. is set in a clean, lablike environment reminiscent of Portal, while Unmechanical uses a world built out of flesh, metal and rock.

The Ball puts players in the shoes of an archaeologist who stumbles upon a series of giant underground cities that takes cues from Aztec structures. In this underground world they discover the titular Ball, which must be used to solve physics puzzles and defeat enemies.

Primal Carnage is a competitive class based multiplayer shooter, which pits a team of human mercenaries against various species of dinosaur.

Finally, Waves is a classic twin stick shooter that is designed to be enjoyed by both newcomers to the genre and skilled players.

The bundle is available on Steam until May 6.
