Description: The Alien threat is targeting tourist hotspots around the globe; deploy your defences, upgrade your arsenal and take control of the battle before the alien menace takes over. Commando Jack's arsenal comprises of four defence turrets, one remote control grenade turret, and three guns which can all be upgraded three times each. Add to this a nuclear bomb and a UAV which provides an ariel view like a gunship, and you've got 26 different items to defend the planet. Also, the addition of three perks to use and swap mid-battle allow increasing turret or weapon power or boosting build points earned, adding another layer of strategy. The four difficulty modes dramatically alter the battlefield and provide different strategic challenges. The nine alien types bring the game alive, with most enemies in the game reacting and changing to the way you play. For instance, the heavy 'Kamikaze alien' walks towards Commando Jack cradling a belt of grenades, but once its nearly dead, enraged, it runs faster towards Jack, with its arms flailing in the air, leaving its grenades open to gunfire!
