I think this game needs much more time. The mechanics and the guns are sound but the gameplay loop and the lack of maps becomes boring very fast. How about we just take down every post we put up saying we are going to 1.0 for awhile? This game is only half done now. I like what i see though in places I will say positive for the price point but yeah... wtf is going on with the maps? I defended one side and when i went to the other side, it was the same fn map, same modifier. This happened too much with the maps themselves and really is a game killer for replay ability. I had the same map 4 times even but with different mods. Nah...you have to fix that. I will watch for now but not happy about the way the gameplay loop runs you out of wanting to play so fast.
You need to unlock things from supply caches to get the full gameplay loop. But once you get things unlocked and figure out a playstyle you like it is a very rewarding experience. The soundtrack is fantastic, and enemy, weapon, deployable, and stage variety are very well done. Each enemy, weapon, deployable, and zone feels unique and adds different quirks to defending the ship. Certain playstyles can be rewarded or penalized depending on the zone and enemies, so having a backup plan is always a good idea, especially if that backup plan sends hot lead down the lane into the enemies ranks. Some enemies are small and slow, some are ranged while others prefer melee, and they're all distinct but easily recognizable. The dev clearly put a lot of care into their game's design philosophy and atmosphere and it shows. Mobility is heavily incentivized and rewarded, but hunkering down on a strategic corner is just as valid as well. Add a friend to the mix and you're gaming! The deployables add an extra layer of complexity to the winding maze-like corridors of the ship's myriad zones. Some are attached to walls, the floor, or even the ceiling. Each with their own damage philosophy and strategic value. Some send enemies careening into death pits, impale enemies who come near, or suck flying enemies into them with a satisfying crunch. But, if all that fails, you can always just line the corridors with explosives and light the enemies up from afar! Hazards pose a unique challenge to both the player and foes alike, so be careful jumping around with reckless abandon, because those pits are evidently bottomless. Windows and environmental objects can be broken for interesting results that can change the tide of a fight in a pinch, and can also provide new methods of traversal or preventing it. There's a catharsis to reaching that final portal and knowing you were the sentry that saved your crew's lives. A legend that will live on to fight another day. Though, I will say Some options for longer runs would be a welcome addition, especially an endless or escalating difficulty mode. Tl:Dr: When My only complaint so far is I can't play it longer, you know it's something special.
Has much potential and CAN be very fun - especially when you have someone to play in coop mode. The newer updates and changes they made for the game gave me mixed feelings though. But i wouldnt say its not worth my money. i definetely recommend only buying it when its on sale (its even on sale right now as im writing this!). I just have one very big problem with the game. The Soundtrack. ITS TOO GOOD! It was good when i played the demo, and it still is good when i play the early access. And its ♥♥♥♥♥♥♥ torture that you cant download the Soundtrack or even just find it on YouTube! Fireblade! If you see this, im willing to pay a small fee if the Soundtrack gets published as a paid dlc on steam! Game is in general a ~6.5-7/10 but with the music definetely 8/10
My honest opinion of SENTRY is that it's not a Tower Defense game with FPS elements It's a FPS with Tower Defense elements While it might be too early to say, I feel like I focus more on headshotting enemies Counterstrike style to wittle them down enough so that my traps feel useful. So in a way, it feels like your FPS skills matter more than Tower Defense strategy. What that means is that you can't expect for your traps to do the most damage, and then finish them off with guns. You actually have to go in guns blazing, do as much damage as humanly possible with guns, then let traps finish them, otherwise you're gonna die. But I'm too early in to know. will update more. The enemies with differently placed weakspots is actually REALLY cool and one of the first times I've seen that in an FPS. So, in a way, it's way more important to use guns to whittle down enemies, before letting your traps finish them off. Edit: Guns have extremely powerful submodes that make the game a lot easier, but still expect firearms to do the heavy lifting. That being said, yes, it's fun, but if it wants to go down that route, maybe implement an ADS since getting headshots is literally WAY more important than putting traps. Also, a map would be nice. As an Indie dev myself I don't want to insist on things that the devs don't want to do, so I'll just say my thoughts. Since roguelike TDs are so rare on Steam, it's hard to fine good ones, and this one is pretty fun.
