Sentinels: Tower Defense with a twist!

The heroic protectors known as Sentinels have been called back into action! This isn't your typical tower defense - Not only will you build turrets and other defenses, you'll be jumping into first person mode and taking bad guys down yourself!

Using the unique skills of Sam, Kat, and Frank, you'll lay waste to the seemingly endless horde. Deploy powerful automated towers, upgrade them to devastating Elite towers, and watch the mayhem. When that doesn’t quite cut it, jump into FPS mode and activate the mobile gun platform - you'll become a deadly projectile as you move between structures, smashing any enemy that dares cross your path. To round out your lethal arsenal, place manually activated structures and rain down meteors and acid attacks. With an ever-expanding roster of levels, face off against 5 powerful enemy commanders, each with their own unique powers and buffs. From stealth to speed to heavy armor, you'll find yourself challenged every step of the way.

Mobile gun platform: Boop, Fly, Kill


Ever been really, really mad at a creep that snuck past your defenses? As in, wanna smash-it-into-a-building mad? We hear you. With the mobile gun platform, you can do just that. When in FPS mode, press spacebar at any time to launch forward and throw creeps into buildings, walls, and even each other. Besides masquerading as a battering ram, you can use the platform to move to any structure on the map, booping creeps out of the way as you go. You can also activate meteor storms, cold snaps, and commander specials without ever leaving the comfort of your cockpit.

Enemies and bosses with dangerous abilities


These creeps really want to destroy the world, and they do *not* appreciate your interference. They'll try everything they can do to sneak past your defenses, strengthen themselves against your attacks, or even attack you directly. Commanders like Guise will grant her forces stealth and allow them to sneak past your automated defenses uncontested. Brick and Aegis will keep their forces stocked up on armor and shields. But beware of Angel most of all - her icy artillery will freeze everything it touches, shutting down your turrets in a flash!

Weapon modifiers: Make the ultimate creep-killing machine


As you advance in the game, more and more weapon modifiers will become available. You have your typical mods like decrease reload time, increase magazine size... but that's just the start. With advanced mods, you can start massively boosting strength of crit damage, or increase energy cost for a massive power boost. Some mods will help you against specific enemies, giving your weapons shield breaking or armor piercing abilities. The more you level up, the more mods you unlock, and even more are going to be added. The sky's the limit!

Hello everyone! Fun news, updates, and a spectacular sale for you today! Sentinels is only $4.99 for the Steam summer sale, and we've worked really hard on one of our biggest updates ever. This is an exciting one for us - we've been developing this game for years now, but this really does feel like a solid benchmark. Made a lot of progress since entering Early Access, looking forward to making plenty more!


We're also working on adding EA-only perks for you guys. Currently working on gun skins, unique voicelines, and confetti explosions, among other things. We'll keep you updated, and let us know what else you want to see!

Now then, onto the new features. A lot of these are difficult to communicate via screenshot, but we can do you one better! We recently did a playthrough of one our encounters in Speed Trap, showing off all of the cool stuff. Check it out below!

We've added an awesome new feature called chrono mode - slowmo activated by pressing shift while in the mobile gun platform. This is a limited resource designated by a blue energy bar - it will regenerate whenever not actively being used.

We've also added a perch, which will place you high over the action and allow you to survey the action below in slow motion. You can freely activate commander specials (hotkeys 1, 2, and 3) and activatable structures while perching, but shooting will disengage you from the perch.


Strategic energy usage has always been important, but it felt bad when you ran out of energy after a hard battle and couldn't even shoot. Along with some other energy changes, secondary (sniper) weapons will now fire even if out of energy. Your increased energy regeneration won't kick in until you stop firing, but this way you can shoot those little guys trying to escape instead of just staring helplessly.

Some fun graphics changes are in too! We updated the fog effect and really like how it turned out - we'll be iterating more, but give Sierras and Into the Pit a visit for the best examples. A proper entrance and exit teleporter has been added as well.


Orbital laser now has a much more visible presence - before, things could sneak by you and it wasn't always obvious when or where the creeps were getting bugzapped. Now the laser will start hitting earlier, and it clearly represented in a deluge of lava melting all creeps in its path. This functions as a bit of an alarm system as well - if you see it activating, you can quickly go over and knock out some of the creeps before the orbital laser reaches them, saving you valuable charge power.

Killstreaks have also been vastly improved - a little badge icon will now show up on every creep killed once your killstreak begins, and the bar will reset after every 10 kills, allowing you to extend your streak. The longer your streak, the more points and orbital laser charge you get, so keep an eye out for those groups and keep your killstreaks up!


We also made a bunch of tuning and balancing changes to make everything more fun, and can't wait to hear what you think. :) The Steam summer sale lasts until July 5th, make sure to pick up Sentinels for all this fun stuff and more!

Thanks so much for reading! Hope you enjoyed, and be sure to follow us on twitter for updates.
