Indie developer David Szymanski has released the retro shooter game DUSK on Steam Early Access. The game is inspired by classics such as Quake, Heretic, Hexen and Half-Life.

The shooter game features three distinct campaign episodes that are inspired by pioneer shooter games from the early '90s.

Players battle through an onslaught of mystical backwater cultists, possessed militants and even darker forces and attempt to discover just what lurks beneath the Earth.

The game features an arsenal of weapons to choose from, including saw blades, dual-wielded shotguns and grenade launchers.

DUSK also features an Endless Survival Mode in which players must defeat waves of enemies and an online arena multiplayer mode that allows players to go head to head.
