Strike Gunner S.T.G (エス・ティー・ジー) is a vertically scrolling shooter video game released for arcades in 1991 by Tecmo.
In the far future A.D. 2008 aliens have invaded the Earth and launched a full-scale war that threatens humankind.
Earth's scientists have built two of the ultimate weapons, the Strike Gunner, piloted by Mark McKenzie and Jane Sinclair to repel the invasion and destroy the alien armies.
[1] The player goes through various levels and stages, usually based around certain environmental elements and faces numerous types of enemies.
At certain points, a stealth bomber (or in later levels, a space shuttle or capsule) will appear to airdrop the player laser power-ups, recharge special weapons, or give a speed boost.
