Our take on Sentinel 4: Dark Star

The extensive upgrade and loadout choices come with a focus on preparing defenses and managing a long tower-defense campaign, rather than centering play on direct unit combat.

What is Sentinel 4: Dark Star?

Lead the Sentinel dropship through a science-fiction tower-defense campaign covering 31 maps, with a separate Endless option for every map.

Protect broad, multi-screen environments and extended routes from aliens whose different traits let them damage, disable, or demolish towers. Three commander heroes reinforce the defensive line, collect experience, and acquire abilities as they advance. Select weapons, gain access to oversized Uber Towers, deploy units along attack routes, and request assistance from the ship, drones, and additional Stronghold systems. Use collected earnings for upgrades that remain available throughout the campaign. Scores may be sent to the Global Nexus, joining a shared rewards drive. SteamWorks provides leaderboards and achievements.
