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.

Its missing fun
it's really fun, but my framerate drops to like 100 (capped at 200 with vsync) in later waves especially in coop (and i have like a pretty good pc so idk why it would be doing that).
Followed this game since Splattercat covered it the first time. The second time he went back to look at it I was convinced to try it out. Co-op wasn't mentioned in his review and was a very pleasant surprise. I only wish there was an infinite mode, or longer runs. I enjoy the game immensely and am looking forward to see it continue.
quite a challenge to begin with but it does get easier (sometimes) further you progress im hoping that this game keeps to its road map and future updates, well worth the money asked for
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
what a great game, the best game i have found it a while, it's loop of unlocking new weponds and traps never gets old and with updates coming out every half a year it is great time to buy the game, overall if you like repetitive games where you get to unlock new traps then it is a must buy.
太好玩了,但是太简单了,在0.9版本我通关过几次就开始自限只使用局内获得的武器和部署物,打不过瘾,仅仅使用初始的武器和前3个装置,再随便升级,打过第一层后就能一路打通,每一层的难度膨胀的太慢了,每一次关卡的体验都十分的同质化。 我从盗版入手的0.9版本,现在买个正版看看有什么新东西,结果更新了什么?新手教程?你浪费产能做哪个玩意干什么。你应该弄一个单局30波次的挑战模式,每一波次获得科技点或新装置,最好像肉鸽一样3选1,场地做大点,怪堆多一点,更强大的空中单位,更强大的地面单位,更强大的boos单位,精英怪和杂毛一起往前冲,再弄个3*3的炮台。用强力的配置对抗强力的敌人,割草就要割的爽。
