If you’re in the mood for some sci-fi gaming, then the Humble Weekly bundle might be for you. It’s got a nice variety of things in every tier. The pay what you want tier gets you Velocity Ultra, QUBE, and Cosmic DJ (in early access). Spending $6 gets you those games as well as The Fall, Strike Suit Infinity, and Strike Vector. $15 or more unlocks The Last Federation. Velocity Ultra, Cosmic DJ, QUBE, and The Last Federation all come with soundtracks. This bundle gives you some solid variety, and if you don’t have anything in the pay what you want tier, I would recommend spending at least a couple of bucks just for Velocity Ultra. I’m not much of a shoot-em-up fan, but I enjoyed my time with the game.
