Viper is a retro shooting game based on classic eighties video games.

Game Play:
You are defending your home planet from wave’s of aliens attacking you and the inhabitants of your planet.

You need to protect the humans from the aliens, they will infect the humans and turn them against you, and once a human is infected they are indestructible and will shoot at you, but don’t worry after three levels the humans will have fought off the infection and return to normal.

Watch out for the mines and replicators in your mission too, there’s also nasty raiders at the end of each level to hurry you along.

Your game is automatically saved at the end of each level.

Controlling your Viper:
You control your Viper by tilting your device left, right, up and down. The more you tilt the faster your ship will fly through the landscape.
To fire your laser, tap anywhere on the screen.

Please post feedback if you enjoy playing the game.

Blast from the Past

Update:- small detail, but would like to have ship thruster's sound, twinkling/shimmering stars in background and anything that can make it closet to the original.. would be much appretiated.

Not quite the quality, graphics and sound effects from the must have 'Williams Defender' 80's arcade classic, but is the closest we have so far and will fill the gap happily for now until someone releases an exact version of the 'Williams Defender' classic that's as good as the Playstation 3 version (the closest yet!).

That said, the Dev has done a rather good and decent attempt here which is close to the original, well done.! Would like to see an 'in game pause' and also the ability to adjust the amount of sideways/horizontal sensitivity.

Quite good

Not a bad Defender-type retro game. Not an exact replica, but if you like the original Defender then this will do the job for you. Reasonable price too.


A great clone of the arcade classic Defender. Well worth a purchase.
