Friends, there are an awful lot of twin-stick shooters on iOS. After a period of relative dormancy, the genre came back into fashion at almost the exact same time as mobile gaming went through the roof and the indie boom kicked off, so it was in a lot of ways inevitable. The competition is so fierce that even the series responsible for getting the genre going again, Geometry Wars, has to be at the top of its game to earn a spot on people’s devices. Geometry Wars 3: Dimensions Evolved ($9.99) stepped up to that challenge, giving mobile players almost the same experience that could be found on consoles and PCs. If you haven’t grabbed it yet, today is your lucky day, as the game has gone on sale for the nice price of $2.99.

Since the game has no IAP, that price not only gets you the core game that Carter “3.5 Stars" Dotson awarded five stars to almost one year ago, but also the excellent Evolved expansion that added a bunch of content including 40 new levels. With the game normally selling for $9.99, it’s an outstanding deal for the price, and one that any fan of twin-stick shooters should jump on. The game hasn’t been on sale since Christmas, and it’s hard to say when it will be discounted again, so start rifling through the sofa cushions as soon as you can if you want to take advantage.
