PowerSlave Exhumed is an upcoming port of the cult classic mid-'90s first-person shooter.
It's from Nightdive Studios, the developer behind the recent releases of Doom 64 and Shadow Man and the upcoming System Shock remake. The trailer is below:
PowerSlave first released in 1996 on the Sega Saturn, and for the time had a unique mix of traps, puzzle-solving and first-person platforming. It acted as a precursor to the likes of Nintendo's Metroid Prime.
