Here is a remake of a true classic, spawning from the days of the Spectrum and Commodore 64, originally created by Hewson Software.

The idea of the game is to get through the five levels of the space pirates base in a strict time limit (about 5 minutes per level) recovering 1500 points worth of cargo on each level (you can find it lying around or get it by killing the little aliens that spawn in most of the rooms). It doesn't really matter if you manage to get the 1500 on each level, but if you do it's worth some bonus points and an extra life at the end of the level. Given how chocka' with enemies the game is, those extra lives will come in handy.

The game is played from a side-on perspective with a flip-screen display that prevents you from going back on yourself. You can upgrade your ship with an orbital mace that kills pretty much anything, a rear firing laser gun and an orbital ship which fires when you do.
