Sol Survivor is an independent tower defense video game developed by American studio Cadenza Interactive.

[1] Sol Survivor is distinguished in part by an interactive "support" mechanic, allowing players to assist their stationary defenses with additional damage or effects deployed from orbit.

Another distinctive feature of Sol Survivor is that it offers multiple game modes, several of which allow players to team up against the aliens.

[2] These include: The single-player campaign places the player in the role of a young commander rising through the ranks in a time of war.

As a member of the Sol Paragon fleet, the player is tasked with keeping the Ascendancy from stealing the souls and other resources they need to continue their conquest of the galaxy.
