Rocket Ranger

Rocket Ranger is an action video game released by Cinemaware in 1988. It is composed of both a strategic map where you oversee war efforts as the game progresses, and various minigames that occur when you advance to an enemy base.

It based on an alternate history of World War II, where German forces obtain a sudden technological advance allowing them to steamroll all opposition with a newly developed superweapon. A century after global conquest, a group of scientists discover time travel, and use it to send equipment back in time in hopes of stopping the war machine before it is too late.
