Trepang2

Trepang2 is a single-player action game where you play an escaped soldier with no memories and supernatural abilities, fighting mercenaries with melee, guns, slow motion and cloaking.

The free demo version is available on GOG.com.

You play as an escaped soldier with no memories of their past life and supernatural abilities. A mysterious group breaks you out from a heavily guarded blacksite, and you must fight back, find the truth, and face a threat even deadlier than yourself.

The demo features an explosive single-player story campaign, superhuman strength and speed, time slow, cloaking, and brutal melee combat. You can also use explosive weapons and take on heavily armed mercenaries in close quarters and rapid-fire gunfights.
