Sol Survivor puts players in command of a colony’s defenses, where the task is to protect both the settlement and its colonists from attacking enemies. Its strategy centers on building a varied turret line, with 26 turret types described as having distinct roles, from cannons and mortars to lasers and automated drones. Rather than leaving every attack to stationary defenses, players can also direct orbital weapons against enemies, including lasers and artillery.
The battlefield can be viewed from a fully rotational camera, supporting both a distant view for planning and closer positioning for precise actions. Ten executive officers offer different combinations of turrets and support, adding another choice to how a defense is assembled. For a change from defending the colony through structured matches, Survival mode sends players against increasingly difficult, randomly crafted waves, with friends able to compare their best times.
The game supports solo play as well as cooperative and competitive multiplayer, with modes including Duo, Versus, Co-Op and Wars, and support for matches with up to eight friends.
