Ollo actually consists of two great 'blast anything that moves' arcade games for only £2.95.

Each game features your efforts to blast your way through the enemy with your ship that has more than a passing resemblance to a florescent doughnut.

This doughnut packs quite a punch in the shape of a forward-firing laser and in Ollo II bombs that you can fire just in front of you.

Ollo I begins on a cratered landscape and a swarm of awful green things that are easily blastered, then it's on to more intelligent red things as well as giant flies that must be zapped several times before they eventually blow up.

In Ollo II your problems are doubled. Not only do you have to blast aliens that swarm around you (and shoot at you) you have to bomb installations.

After a brief rest mindlessly zapping aliens in deep space the action really hots up on what looks like a starship or base complete with flashing lights to bomb, aliens to blast and avoid and gun emplacements that track your every move.

A ridiculously addictive game, at an even more ridiculous price. Go buy it immediately.
