Free-to-play FPS Warface will allow players to customize and upgrade their weapons in real time, as shown as this latest trailer from Crytek and Trion Worlds.
From the trailer, FPS fans can expect the standard accouterments for their guns: laser-dot sights, suppressors, rail grips, and under-barrel grenade launchers, just to name a few.
Warface is slated for release in the West this spring, and is currently in beta testing.
