Battlezone 2 is a RTS/ FPS. You can build bases, and walk inside them to get to the terminal to customize the ships, or mechs, Upgrade your buildings. Hijack enemy vehicles by sniping their cockpit. There are also great addons, and Mods to the game as well...I still play it on lan, and online, real fun for months I say....or up to a year....*cough* Been playing it forever.
