Evaluation

SENTRY remains in Steam Early Access, with Fireblade Software actively developing it toward a 1.0 full release. The studio has shipped five major updates since Early Access launched in March 2024, the most recent being "The Prologue Update" (Major Update 5) on September 17, 2026, which added a new narrative prologue split across two missions, three difficulty modes, a loadout specialties system, an overhaul of all core enemy types, a new enemy, and full gamepad support. Just one day before this assessment, on September 28, 2026, the developer published a detailed roadmap update laying out the remaining work before full release. The primary upcoming addition is "Vanguard," a new campaign where players take the fight back to the enemy, shown with concept art of the final sector. Alongside this, the developer plans to rework the Starfarer campaign's ending, add cinematic sequences to each campaign's conclusion, and add visual variety to each sector to reinforce the sense of journey. Standard 1.0 additions such as achievements and Steam Deck verification are also on the list. The developer estimates full release will arrive in Spring 2027. The roadmap also confirms post-release plans: at minimum one free major update after 1.0, consistent with how they supported their previous game Abandon Ship for years after its launch. Potential paid DLC is mentioned as something to consider once the 1.0 work is complete, depending on community interest. Development is active, thoroughly communicated via monthly developer transmissions, and progressing on a clearly defined schedule toward full release.

About this game

As a member of the SENTRY Defense Program, you have been thawed from stasis to protect your vessel as it flees across space.

As you choose your escape route in the Navigator, encounters with alien vessels are unavoidable. They will board your ship and attempt to fight their way through different subsystems to destroy the Core.

Your SENTRY must thwart the enemy by bringing to bear an arsenal of potent ranged weaponry. Even with the best shooting abilities, holding back the hordes is only possible by deploying traps and turrets - and if all else fails, utilizing environmental destruction to stem their advance; a well-timed shot could vent aliens into space, a closed blast door could buy you time to set up new defenses.

SENTRY features a singleplayer campaign with the option to have an online friend fighting alongside you in co-op.

Should your SENTRY fall in battle, death is not the end. Another member of the crew will be thawed from stasis by the SENTRY Defense Program, ready to continue the fight.

Even if you fail to defend a level, defeat only changes the strategic landscape in the Ship Overview, forcing you to make new decisions on where to make your next defiant stand.

As long as there is a surviving SENTRY and the Core remains operational, your skills in combat mean victory can always be grasped from the jaws of defeat.

SENTRY aims to carve out its own path in the Action-Defense genre by featuring a campaign where your choices and performance matter. Battles are not one-off events, defeat doesn’t mean replaying a checkpoint. Everything feeds into the ongoing battle for your ship’s survival.

A SENTRY is fast, responsive - and therefore powerful. Deployable traps, turrets and environmental destruction opportunities are needed to supplement this power when facing near-overwhelming forces of reactive and aggressive enemies. Successful escapes will need to utilize a mixture of skill and planning, with discovery and upgrading of new equipment providing an edge in combat.

Combining all these elements evokes the feeling of being a beleaguered and outnumbered SENTRY. On the journey you may lose battles, but you can win the war.
