I bought Steamworld Heist off of someone in the trading forum over the weekend. It's a lot of fun. Gameplay videos should give you a pretty good sense of what's going on, but it's turn based 2D shooting. You have missions you choose from on a world map, but the levels are procedurally generated. Scour the level to find water (currency) and weapons/items and the characters in your squad level up for new abilities and stuff. Very different from Dig in how it plays, obviously, but has the same awesome art style. I thought I read that it wasn't cross-buy, but the code I redeemed gave me both versions. *shrug*
