Time Soldiers

It's a hot hit straight from the arcades to your Sega System! Team up with a friend and join a battle that crosses time and space. The evil space tyrant Gylend has attacked Earth and turned five of your friends into energy balls. As the leader of the Earth Command Troopers, your job is to track your friends down and get them back. The problem is, Gylend has scattered them across time in different parts of Earth's history.

You have the D-Scanner... a device that can guide you through the river of time! You have shoulder-mounted cannons and access to even more powerful weapons. But Gylend has the might of the creatures of history turned against you! From cavemen to armored attack craft, all will fight you with everything they have.
