Aksys Games has released Aegis of Earth: Protonovus Assault today for PlayStation 4, PlayStation 3, and PS Vita, after quietly confirming the game’s release date five days ago.

The Acquire-developed game is available both at retail and via the PlayStation Store, and it will cost $39.99 on PlayStation 4 and $29.99 on both PlayStation 3 and PS Vita.

Featured above, a new trailer was released to celebrate the game’s western release.

Here are the game’s key features:

• Defense is the Strongest Offense
  Engage in dynamic city defense via revolutionary gameplay mechanics in which you rotate your entire city to aim weapons and take out monsters! Leave no quadrant untouched as you spin 360 degrees in search of would-be destroyers!
• Immersive Commander Experience
  Command and level up a huge variety of units and gargantuan weapons as you hone your tactical skills. Immersive gameplay puts you in the center of intense combat. Seize the initiative from your enemies and decimate their ranks as a robust cast of characters lend their support to the cause!
• Massive Content Keeps You in the Fight!
  An intense 20+ hour campaign ensures you’ll have your hands full as you battle through 23 epic missions! Fend off 15 species of relentless enemies that will not stop until your city is reduced to rubble!

In the game you control a city in which you have to make use of tower defense-esque mechanics, where you defend against alien invaders. Your city will level up as more people flock to your leadership, and you’ll have to literally spin and make use of your tactics to overcome your enemies.
