For 48 hours, GOG is giving away free copies of the classic real-time strategy game Total Annihilation: Commander Pack.
Released in 1997, the sci-fi RTS comes from Wargaming.net, the makers of World of Tanks and World of Warships. The Commander Pack includes Total Annihilation and its two expansion packs: The Core Contingency and Battle Tactics.
Here’s more background on the game’s story from GOG:
What began as a conflict over the transfer of consciousness from flesh to machine has escalated into a war that has decimated a million worlds. The Core and the Arm have all but exhausted the resources of the entire galaxy in their struggle for domination. Choose your side, build an army, and crush your enemies on huge, three-dimensional battlefields. And remember, there is no such thing as “too many guns!”
