Good fit

Skip it if you…

Saves you a refund
  • Players seeking a campaign longer than 20 levels may find the main scenario limited

Our take on Sentinel 3: Homeworld

Tower defense players who expect to manage defenses from a fixed viewpoint may bounce when the power armor becomes part of the battlefield. The shift from placing or upgrading defenses to personally executing attacks is the specific point where a hands-off play style meets friction.

What is Sentinel 3: Homeworld?

Sentinel 3: Homeworld is a sci-fi tower defense game set on an alien homeworld.

Its campaign contains 20 levels, with more than 20 unlockable options including turrets, orbital ship weapons, automated drones, and abilities. A commander unit gains levels and abilities during play, while the Armory allows weapon loadouts to be adjusted for each mission. The power armor adds direct battlefield attacks that support the defenses. The game includes a new commander, enemies, campaign, weapons, and other content. Endless modes are available on every map. Classic mode provides a skill-based format for score competition, and Steam Achievements are included. The soundtrack features music by Specimen A.
