StarShip Troopers : Last Defense is a free 3D RTS game using the Glest engine, it is set in the StarShip Troopers Universe.
This is essentially SST:LD 2 with a few little bug fixes and multiplayer. Including LAN & I.P Address Connect. This works very much like the old SST:LD 2. This is not an installer but a ZIP file which must be extracted.
an awesome game
