Why am I in shock? Well, wouldn't you be if you'd been away fighting aliens only to find it was all a decoy, and the earth had been taken over in your absence?

You find yourself on a grid, with some static triangles that deflect your shots. This makes killing the aliens quite an art, even though they are pretty docile.

On level 5 they speed up and fire indiscriminately.

The sound, a fast throbbing noise, is good and the effect of the screen flashing white when a triangle is hit is excellent.

The game is let down badly by the poor graphics and the lack of variety of aliens - there are only three types.

It's difficult to position your ship in a particular column because the keys are over-responsive. One touch and you move three or four spaces. However, it is a logical choice of keys.

I doubt the game's lasting appeal, even with the different skill levels, because it can become monotonous. But it's certainly fun to play for a while.
