The game will be offered as a form of closed beta and will grant some bonuses to PlayStation Plus subscribers.

If you aren’t familiar with Orcs Must Die! Unchained, here’s the official description:

In Orcs Must Die! Unchained gamers play as the powerful War Mage, magical Sorceress, or brutal Blackpaw, and can unlock a lineup of other awesome heroes; each with unique powers and abilities. The key to protecting your fortress is to build an impenetrable gauntlet of traps to hack, grind, flatten, gibletize, and incinerate foes. Players may go at it alone or in teams of three, all the while ensuring that the ugly, greedy, vicious Orcs don’t make it into the Rift.

The game will release on PlayStation 4 on June 18th. If you are among PS Plus subscribers, you can grab a Plus Pack that adds  in-game currency, skins, consumables and other bonuses. Orcs Must Die! Unchained is a free-to-play title, but the official PlayStation blog describes this release as a “closed beta,” so it might take a bit until everyone gets inside.
