Orbital Guard drops you in the hot seat of the Mars planetary defense station, shooting down wave upon wave of asteroids and alien threats. In high quality, pre-rendered isometric, defend fleeing escape pods, upgrade firepower, unlock killstreak super weapon rewards and face the final wave in this intense arcade action defense shooter.
A high quality flash game with two modes (regular and survival). Weapon upgrades acquisition system (automatic upgrades as you gain points) seems quite interesting. Also, there are 4 superweapons, each one distinct.
The boss fight at the end of the regular mode was a little surprise. Could have been more bosses in-game. ;-)
