Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We want your feedback NOW, not later. ;)
We're just a two-person team at MindWalker Games, and Sentinels has been a labor of love for the past 5 years. And while we're happy with the progress that we've made, we want to work together with the community as we continue development. We don't want to be a 'my way or the highway' developer - this game is being made for you, after all. You should have a say in it!”

Approximately how long will this game be in Early Access?

“We’re aiming for late 2019.”

How is the full version planned to differ from the Early Access version?

“More levels, structures, weapon mods, enemies… more everything! There'll also be a much better tutorial, and of course a few metric tons of polish.
You'll also notice a lack of EA-only features in the fully released game… because everyone who joins up early will unlock a bunch of exclusive stuff that no one else will.”

What is the current state of the Early Access version?

“Solid… wait, no, liquid? Now it’s gaseous… it’s getting hot in here!!

Dad jokes aside, it’s stable and the framerate is pretty good. We have most of the core mechanics we want in there, and people seem to be having fun.
There’s a lot to learn in this game - but we’ve been working on this for so long, we sometimes can’t see the forest for the trees. Having new eyeballs are helpful, so you can tell us what’s well explained, and what’s… slightly less so.
Oh, and there are bugs... that's an exciting metagame we added just for Early Access players. :)”

Will the game be priced differently during and after Early Access?

“Yes, early access players are receiving a hefty discount (as well as 7 karma points and a virtual hug). It will likely double before release, so now's a good time to get it!”

How are you planning on involving the Community in your development process?

“We want the community as involved as possible, this game is for you guys! You can find us on twitter, indiedb, and facebook; other than needing sleep on rare occasions, we’re always accessible and want to hear what you have to say.”

New beta - Skyguard

For instructions on how to join the beta, click here!

A new beta is here, with a brand new mode – Skyguard! Pure tower defense, filled with new abilities and soul-munching wraiths. Allow me to give you a quick tour of all the new stuff (and some bugs, because who doesn’t love bugs)

To start off with, here’s a recap of what we’ve added in the past few months. Want some damage over time? Wanna explode some creeps? Your wish our command! Lasers and flamethrowers will overheat enemies – and if they die from that heat, then they’ll detonate in a big ol’ explosion and take their buddies down with them. Cold snap also does cryoshock damage now – cool down a group of superheated enemies and watch them shatter.

The old plasma beam got a BIG upgrade, and we also added in a fun little sniper’s nest tower that can shoot from any direction.

Skyguard is pure tower defense – no guns! To compensate for the power loss, we boosted the power of all your tactical attacks, as well as the turret power overall. The drops can either be picked up and activated from the gun tower menu, or alternatively you can right click on them to use them as a regular bomb – they don’t despawn, so you might find it helpful to just leave strategically placed bombs towards the end of the path. Be careful though, the creeps can run into them and move them around (or even drop them off cliffs if you’re unlucky) so use them wisely! To make this a little easier on you, we also added a tractor beam (activated with right click) to lift up pickups that might have fallen in an unfortunate place. You can also left click with the grav beam to activate the rail gun - a powerful projectile that can wound enemies and bosses.

Enough with the tower talk. Now for my favorite update of all – meet the Rift-wraith, a lovable soul muncher that you can unleash on any poor unsuspecting creeps. While he can only live in this realm for a few seconds, every kill makes him stronger as he moves along to the next one. Feed him well and he will reward you with a VERY handsome killstreak. As a universal commander special, you can unlock him in the store!

If you wanna get a little sadistic (if you can get more sadistic than a souleating hellbeast) you may find our gravity bomb a fun addition to your arsenal. Perfect on small enemies, simply drop and enjoy the chaos. You can also use this to gather enemies closer together and make a nice snack for the wraith!

As an avid lover of tower defense, I’m thrilled that the game finally came together enough to be both a tower defense and an TD/FPS hybrid in its own right. I can’t wait to see what you think! And if you’re a reviewer or streamer who thinks this looks interesting, please drop us a line! We’d love to work with you and get your opinion of Sentinels and Skyguard.

Happy new year! New build!

Merry Christmas and Happy new year!! We bring a wonderful gift for you - a new build, one long long overdue! We’re in the middle of revamping the entire tutorial, because unlike all the other little changes we’ve made in the past year, this one is big. Huge. Amazing. You know what it is?


You heard it right. We have FLAMETHROWERS NOW.

Four new towers have been added to the game, along with a plethora of changes to enemy firing, FPS mode in general, commander specials, shielding… just about everything is getting an upgrade, and my god I cannot wait to show you.

We have Pyro, this psycho little tower that will likes to say ‘#*&# this area in particular.’
Fire not your style? That’s cool. We got lasers too. And sniper’s nests.
“We want something new” I hear you say. Well, my dear imagined audience, have I got the tower for you!
Meet the Magno Bombs.

They chuck out magnetized balls of death. Which is fun on its own, but in FPS mode… your gun platform is magetized. You know what that means? Yup. You get to make like Zenyatta and throw your balls in people’s faces. Go forth and make things explodey, my friend!

All of this aside, we’ve made a multidude of changes. Shield got a visual overhaul, and it also has this cool pulsing thing that happens whenever you catch bullets in it, or if you get a powerup. Speaking of powerups… we added lots!!!

The adrenaline bombs are a thing of the past – now, we’ve got reload crates, tower boosting crates (think steroids for your turrets) and this awesome charge crate that turns the next enemy you boop into a bomb.

I do apologize for the lack of updates – we’re only a two person team here at MindWalker games, and I’m the only one on PR. Life was very much on the difficult side lately – unexpected expenses, work stress, and other troubles coalesced into an unholy trifecta of difficulty that knocked me out of the indiedev saddle for awhile. But I am happy to report that we are back and better than ever, and I cannot WAIT to show you all we’ve got in store.

The tutorial has been updated a bit, but we're still iterating on the shield and firing introduction. The beta will be updated in a day or two with added help, but for now here's what you need to know:

Activate shield with right click. Any shots you successfully block can be deflected back against the enemy. Use left click to discharge any built up shots back at the creeps.

WASD can be used to navigate at all times in FPS mode.

Yellow pickups = haste boost for the next tower you land on
Purple pickups = Quantum charge - next time you boop a creep with your shield up, he'll charge up and explode.
Green pickups = Targeting power. Click on an enemy in tactical view and your towers will all target him. Eliminates ground/air restrictions on that enemy.
Loot Crates = Full ammunition recharge

They can all be shot instead of picked up, and they'll just explode like a regular old bomb.

Hope you all had a wonderful holiday, and have fun playing!

About This Game

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!
