Onslaught from Space for iPhone

This might be fine if you want to use all of your missiles at one time before clumsily switching back to lasers, but going back and forth between weapons is time consuming and confusing. I ended up just continually buying laser upgrades, opting to strengthen my most user-friendly option instead of complicating things with multiple weapons.

Despite that shortfall, Onslaught from Space is mostly intuitive and pretty enjoyable to play. And at $2, a good deal for any lover of arcade games as well.
