D3 Publisher has launched the official demo or “Prototype Ver.” for Custom Mech Wars, their new third-person mecha shooter.

The playable demo for Custom Mech Wars is now available free over on the PlayStation Store, for PlayStation 5.

Here’s a rundown on the demo:

This prototype version of the game is a part of the game under development. The content of this prototype version may differ significantly from that of the full version. The prototype version does not support transfer of saved data to the full version of the game.

Take customization to the extreme with the Omega Customization System and battle with one-of-a-kind combat units in this all-new third-person shooter mecha game.

Build one-of-a-kind mechs using the Omega Customization System!

Not being restricted to bipedal builds, you can freely customize your mechs to include multiple heads, legs, and arms in whatever positions and angles you choose. Depending on the parts you use, the parameters will vary wildly, so you can build mechs with whatever abilities and fighting styles you wish!

Battle with Omega Customized mechs in this thrilling third-person action shooter!

Arm your custom mech to the teeth with every weapon imaginable and blast your way through oncoming enemies. Experience the heart-pounding mecha action that only your Omega Customized units can provide. Destroy enemy units, collect their parts, and customize your favorite mechs even more. Complete a variety of missions as you battle, customize, and then battle and customize some more!

Join forces with other players online in the competition between Omega Customized mechs!

This game supports online multiplayer. Up to four players can cooperate to complete story missions just like in single-player mode. Not only can you experience the rush of tackling missions with friends, but you can show off your favorite mechs you personally customized.

Custom Mech Wars is set to launch on December 14th across Windows PC (via Steam) and PlayStation 5.
