Oldschool Blast is pure retro-style with a similar gameplay as the classic version of Space Invaders but improved with power-ups and upgrades.
In "Oldschool Blast" you have to destroy the hordes of advancing aliens by shooting everything that moves. An old-school shmup (i.e. shoot’em up) game that gives you a better feeling playing on a phone/tablet than you’d have by trying an emulator. Just as the classic version, alien ships drop bullets and destroy you, from time to time an UFO "drops by" to drop some bombs right on you and finally there’s also kamikaze ships that sacrifice while trying to destroy you.
Here are the features that you will enjoy in "Oldschool Blast":
The game is available for free on Google Play and you can see it in action on Youtube.
