Blast your way though planes, trains, blimps, tanks and large bosses using a selection of upgradable weaponry.
Thunderbolt is a vertically scrolling arcade shooter in the spirit of the old coin-op classics. Shoot and dodge your way through waves of enemies. Grab the power-ups to boost your fire power, use smart bombs to blast your way out of a tight spot, or save them for the boss battles to inflict heavy damage.
But things are not what they seem. Someone is feeding the enemy futuristic weapons. What surprises await in the later levels?
