Battletech for Sega Genesis is a mecha war game. It can be quite difficult and will take some time to master, but it's really worth mastering.
Gameplay. You control a mecha, which you will use to accomplish certain missions like destroying some key enemy structures and other enemy mechas. What I like about it is that at the start of each level, the mech can be equipped with 3 weapons of your choice.
Two man team. Aside from being played by one player, it can also be played by two players. That is, two players will be controlling the mech warrior.
It's action packed and fast paced. All in all, I would highly recommend buying Battletech for your Sega Genesis collection.
