Im currently making a remake of the 1982 classic Time Pilot. The player assumes the role of a futuristic, time travelling jet who travels through different eras fighting hordes of enemu aircraft and defeating bosses, all the while racking up their score!
You begin in 1910, fighting biplanes and blimps.
In 1940, you fight spitfires and B-52s.
In 1970 you're up against Apache and those big helicopters with two rotatory blades.
In 2000 you fight against fighter jets and stealth planes.
Finally in 2030 you must fight off an alien invasion (small and big ships).
Once you complete 2030 you restart only it is harder and faster.
here are some screens;
This one shows you travelling through time.
coincidence? how about pure cosmic convergence!
