Hold on to your hats and get set for a non-stop, all-action futuristic blast-'em-up of mega proportions.

Carefully, chopping and changing between your turbo land cruiser and your mach speed jet fighter, your task is to battle through an incredible alien onslaught over sixteen zones, at the same time collecting essential supplies to rescue Captain Xod's Federation Ship.

Keep a close eye on the terrain, as you'll need to swap crafts very quickly indeed to pick off the different enemy forces, as well as to pick up much needed weaponry along the way.

Halfway through each section, approach the Sentinel with care. He's not easy to kill. Nor is the end of level Sentinel. There's only one way to destroy it, so attack with care.

The scope and presentation of Xenon are both excellent, making it a superb bargain on the budget label for shootie freaks.
