About SENTRY

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.

Noice. It would be even better if material cost of deployables and the damage of deplyables are lower, so that players will have to use the whole map more.

There's a lot to like about this one if you're a fan of the Tower Defense/Shooter genre but there's a lot of room to grow. The Good: The overall gameplay loop is fun and if you're familiar with rogue-likes, tower defenses, and shooters, you're going to feel happy with what you're getting here. Sound design is great, the story so far is neat, and the overall experience has been satisfying. The Bad: The camera shake is horrendous in this game given how many different things cause a camera shake, the severity of the shaking, and everything is on by default. What I'd Like to See: - Endless Mode. Your run ends after 3 sectors and there's no choice to push on. - Crew giving some kind of bonus. As of right now, picking up extra crew members just represents extra lives in a run, but I've yet to need extra lives at all. This makes avoiding picking up extra crew members an easy choice. This also makes the Medical ship the least optimal to run. Picking this ship means I'm planning for failure, where the other ones reward me for success. I wish they gave me some kind of bonus for each crew member I have alive whether that be extra materials, resources, or just a discount on repairs. Surely…

When I played this a year ago i thought it was decent. Knew it would be very god with a few updates. Trying it now, I feel vindicated. Much more fun now overall, especially with the tech/perk system. Would recommend.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.
