March 30, 2005 - Namco today announced that it will be publishing Rebelstar Tactical Command for the Game Boy Advance. The game, a turn-based strategy title from the makers of X-Com, is being prepped for a late Summer release.

Developed by Codo Technologies, Rebelstar Tactical Command puts players in a futuristic situation where Earth is under control of the Arelian Empire. Rebels have risen to fight back against the evil alien scum, and it's up to players to take command of the troops in order to eradicate the Arelians and take back the planet.
There will be four modes of play, including Campaign, Skirmish, Hot-Seat Multiplayer, and Link Cable Multiplayer. In hot-seat multiplayer mode, a replay option lets players review the opponent's last turn so that he's not hiding his players completely from view.

Watch for a release of Rebelstar Tactical Command this August. Hit the media links below for the first screenshots.

I'll buy it. I wish it was coming out for something with wireless multiplay (even though it is turn based).
