About

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.

很不错这游戏,这游戏刚出的时候,一直观望直到大概2024年4月19日下了个盗版来玩玩看一看,还不错蛮爽的,直到2025年看到更新了两人联机才买的游戏,联机也不错不会太卡,聊天功能也没问题,退出刷关也很容易加回来,就是困难三大关打得久一些大概一关一小时,还有刷关可以用来刷那个蓝图,如果是有了的蓝图可以直接退出再进,他又会回到选择界面了,可以快速刷蓝图,在觉得那关打得不好也可以刷关 这游戏我玩下来就机枪轮椅炮台一拿,再拿个好用的枪基本就能通关了,炮台堵门防漏怪,散弹炮台虽然距离近了些但也行,有点控制,在拿物质和医疗补给箱,妈妈再也不会因为我没弹药和生命而担心了 枪就那几种,比如初始枪MP-45,90发超高弹匣,但后期怪多,数值高了比较乏力,我个人推荐和平使者,双连喷散弹24一弹匣(实则12发,因为双连喷),还挂了个闪光弹发生器,还有就是AR44突击步枪42发一弹匣,还有个榴弹炮发生器,还有就是EM.BR-01 电磁爆炸步枪,单发伤害高可右键引爆射在敌人身上或物体上的子弹,好像是12发一弹匣了,我也主要玩这些啦 买回来是有点不习惯,毕竟地图换了,比如以前全部敌人一条长线的食堂变毕竟短了,还有那个敌人靠近出口是的预警任务这狗,怪上楼梯走到上面的平台就算次要任务失败了也是神了 底子很不错的一款游戏,但是还是有待改进,我还是希望出个测试房间,更好了解武器满级后的手感和一些敌人图鉴,更好让我做视频发网上(doge

i've mixed feelings on this, but since i love the feeling of "FTL but you're playing as one of the security crew", and I have no doubt people get a lot of good out of this game, I would generally recommend it. HOWEVER, I personally have found my experience so far to be grating. This is baffling to me, as all other reviews seem to remark on the difficulty going from easy to breezy depending on whether you use turrets or not, and while I have prayed for every hour spent, I havn't managed to find any of these mythical machines. I have been relegated to putting little traps on the floor and walls, and then done the spray-and-pray until I reach a level (sooner rather than later) where the enemies would either go straight past me or ignore my cool Quake-like movement and simply stomp me into the ships hull. While the "Orcs must Die"-esque deployables (further enhanced by environmental kills) are great and fun, they don't seem particularly effective, and the best choices seem to be anything with crowdcontrol, so that you can shoot them with your lil gun. In that vein, my best run saw me reach midway through the 2nd zone by solely upgrading an smg i found, but it seemed a little boring to turn my tower defense into a just-about-decent FPS. Whatever I am doing wrong compared to my peers, it turns every run a hunt for any and all supply pods that might provide equipment that might buy me another twenty minutes of uninterrupted playtime, but so far no success. Perhaps further updates to the game will help me become someone who can breeze this. Recommended for people who love the concept and can endure some hard times.
Einfach Schmutz.
Самое полезное обновление - это обновление где персонажу добавляют ноги в игре от первого лица Игра то норм, но миссии мало, надеюсь разработчики будут потихоньку развивать свою игру, а не забрасывать Лично как по мне, я бы добавил маршрут от земли, ну...банально до марса, с марса встаешь на защиту базы, от защиты базы ты уже летишь на другую планету, или в другую солнечную систему, с какой нибудь историей что типа "Ещё не все потеряно" придумать новые корабли и локации в них, я знаю что говорить легче чем создавать, но я лично просто выказал свое ни кому не нужное мнение
lo recomiendo muchisimo muy buenas mecanicas pedire un reembolso por que mi pc es una tostadora pero nada grave para una buena pc
The game is pretty fun, it's a nice challenge to defend each sector where enemies breach but it does get very overwhelming very quickly. Another issue I have is why is the CO-OP only limited to 2 players? Why not make it 4 player CO-OP like every other game? Overall, very disapointing but very promising
Все збс только ♥♥♥♥♥♥♥ оптимизация ебёт мозги( разраб прими во внимание !!! )
I find this game very fun, even in it's current state, been here since it released and has only kept getting better some things feel pretty unfair at first, specifically the hunter ships, but once everything starts making sense it gets really fun there's not really "a reason to play" though, apart from unlocking all the blueprints and character skins there isn't much to do other than playing the game for the sake of playing the game one thing I def would recommend is that I don't think you should use the blueprints, just upgrade your weapons and get new stuff from the caches, mainly cuz if you get the turrets and the shotgun/rifle every run the game will feel stale rather quickly, those items are both fun and good but the game will get boring if you use them and nothing else
