From June's Humble Choice

Co-op roguelike action
The classic multiplayer roguelike, Risk of Rain, returns with an extra dimension and more challenging action. No run will ever be the same with randomized stages, enemies, bosses, and items. Play solo, or team up with up to four friends to fight your way through hordes of monsters, unlock new loot, and find a way to escape the planet.

Constant battles and incredible bosses
With each run, you'll learn the patterns of your foes, and even the longest odds can be overcome with enough skill. A unique scaling system means both you and your foes limitlessly increase in power over the course of a game--what once was a bossfight will in time become a common enemy.

Old favorites return and undiscovered challenges await
Myriad survivors, items, enemies, and bosses return to Risk 2, and many new ones are joining the fight. Brand new survivors like the Artificer and MUL-T debut alongside classic survivors such as the Engineer, Huntress, and--of course--the Commando. With over 75 items to unlock and exploit, each run will keep you cleverly strategizing your way out of sticky situations.
