What the developers have to say:

Why Early Access?

“Want to help us build a cool action tower defense game by shooting bad guys in the face? Let's do this!
Sentinels has years of development behind it and is nearly feature complete, but there is still much work to be done. Early Access, for a truly indie developer, is simply the best way to get feedback and support while staying focused on building a great game.”

Approximately how long will this game be in Early Access?

“Planning on releasing end of 2017, but best answer is it’ll be released when it’s done, and not a second sooner.”

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

“More levels, more structures to build, more loot mods, more enemies and a good single player campaign that introduces the mechanics smoothly. There are also some experimental additional game modes that will likely be added and will make it into final release if they test well.

And, of course, a few metric tons of polish.”

What is the current state of the Early Access version?

“The game has been stable in our tests, and framerate is good on desktop gaming rigs, but there have been reported issues with laptops. There are about half the number of levels intended for release, but there are multiple challenges for each level, so there’s a good amount of variety right now. The difficulty might be a bit high right now... but you like a real challenge, don't ya?

Oh, and there are bugs... that's the 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 discount (as well as 7 karma points and a virtual hug). It will likely go up about 20% before release.”

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

“While we have a tiny team, we’ll stay tuned to the forums and do our best to respond to and evaluate feedback, and never miss those awesome ideas community members can bring to the table. There are some additional development tools that will be active in the game for early access players, helping them contribute easier, if they wish.”

Beta patch notes

New beta build released 9/1/17 - working from your feedback, we've started to make some sweeping changes. Active paths have been heavily decreased to both get away from the chaotic feeling of later levels, and to work well with the new themed encounters. We working on a better rampup of difficulty into the game, as well as a clear goal to strive for. Expect several more patches as we continue making improvements! Changes made so far:

Added spawn preview dialog that’s visible when preparing for assaults
Added visualization of elite spawns on assault preview.
Added several new themed encounters.
Disabled path displays when there are no paths active for the assault.
Made enemy passive abilities apply to groups, rather than to enemies randomly.
Blowing up shield projector does more damage.
Increased time it takes for shield projector to generate pulse.
Added shield generator chargeup audio.
Fixed bug in critical hit multiplier
Changed elites so they’re explicitly created in group.
Refactored elite distribution, to get better distribution of elites.
Reduced cooldown on activatables.
Fixed elite and passive abilities for Aegis.
Removed Stryker from commander lineup.
Fixed elite and passive abilities for Angel and Guise.
Lowered Sam’s primary fire machine gun damage.
Level reward display modifications
Improvements and fixes to Pit
Marked Quarry as under construction.

And a boatload of little fixes per usual.

Devlog accompaniment for Beta Build

Our beta build went live yesterday, and today you can find our latest devlog post over on IndieDB! It gives far more detail about some of the new features of the build, and plenty of helpful information as we continue work on implementing tutorials.

There's also a new playthrough video of Snow Path included, and other info as well. We'll be posting progress updates every two weeks or so - or more frequently, if we have a lot to share :). Enjoy!

About This Game

You like exciting FPS Shooters? You like Tower Defense? Want to customize weapons into your own personal killing machines? Then this game's for you.

Deploy automated and manually activated defenses to crush, pierce, burn, freeze and otherwise thoroughly decimate the relentless hordes of enemies. Jump into the fray yourself with powerful first person weapons like machine guns, shotguns, missile launchers, artillery… almost too many ways to humiliate your foes.

Still not enough ways to misbehave? You can customize loadouts with gear pillaged from your enemies, or rewarded from your heroic performance in the multiple missions offered for each level. Still need MORE? Fine, you can also also get modifications for your gear, increasing range, speed, and even force applied, just in case you wanna ram enemies into buildings - or each other. You can watch our level quickplay here.

  • Build your defensive web with a variety of automated and manually activatable turrets.
  • Jump into the fray with powerful first person weaponry. Choose from grenade launchers, lockon missiles, machine guns - just to name a few.
  • Customizable mods bring more destructive additions to the table - with options like force, phasing, and armor piercing, the strategic possibilities are endless. Personalize your weapons and towers to the highest standards and take the baddies down with grace.
  • Defend an ever-expanding roster of levels - 10 maps are currently available, 7 which have multiple challenge and endless modes. At least 6 more levels are actively in the works.
  • Level up and increase your rank to unlock more weapons, mods, and other perks.
  • Face off against 5 powerful 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.
  • Early Access Special! All EA players can access developer mode. Should you choose to activate it, you'll be given incredible control of the game. Bump up strength, speed, and frequency of enemies if you like a challenge, or increase the commander ammo pool if you want more fps action. You can adjust pacing, as well as toggle various game modes as we move forward in development. You can use these tools to give us personalized feedback and perhaps see your personal changes implemented ingame. All of this and more is available - the power is in your hands.
  • Steam Trading cards are coming soon.

Still curious how it all fits together? Check out our post here... or just play and find out for yourself. :)
