If for some reason you were holding off on downloading Fish Labs' Galaxy on Fire 2 [Free], you officially just ran out of excuses. For the first time ever, this space shooter is totally free. If you need that extra push over the edge, you could check out our review, but really, you should just download it.
Galaxy on Fire 2 comes in two varieties these days, the free version is the "standard definition" one. If you've got a newer device and want all the fancy (and huge, in a file-size sense) graphical effects, you'll need to spring for Galaxy on Fire 2 HD [Free]. So, if you've a new iPad, give the free version a shot, and if you like it maybe download the HD variety instead?
