As the commander of the defense of Earth's first colony, players must determine the best strategy to save the colony from the tens of thousands of alien machines that are rapidly approaching. Each victory against the enemy expands the colony to a new part of the planet which, in turn, is met by an increasing aggression by the enemy.

In Siege of Centauri, players defend their colony against relentless waves of thousands of enemies. In the campaign, they will follow the story of Earth’s defenders and progress through increasingly difficult scenarios in their mission to protect the colony at all costs. Dozens of upgrades are available for the defense towers, leaving the player with important decisions regarding how best to equip their defenses on each map.

"With tens of thousands of enemy machines pouring toward your base, we wanted to give players a very new experience of what it means to defend themselves against overwhelming odds," said lead designer Derek Paxton. "In addition, we’ve incorporated several strategic elements into the genre, including defending resources and deploying rapid response teams to battle. Our goal was to provide players with difficult choices about which areas to defend and which areas to let go, leading to greater strategic depth.”

“It’s always been important for us here at Stardock to put customization into the hands of the players,” said Paxton. “Now, people who have always wanted to design their own tower defense games can create their own maps and missions.” Players can learn more about how to make their own scenarios with the Modder’s Guide.

Players can also create their own missions with the Scenario Workshop, then upload them to Steam for others to try.

Currently available through Steam Early Access and Stardock Store, Siege of Centauri will be launching on September 12, 2019 .
