Lightphobe

Lightphobe is an asymmetrical team-based PVP game that blends stealth action with fast-paced shooter gameplay. Choose between defending the earth as a squad of well-armed Soldiers, or join the dark horde of ethereal skeletal creatures known as the Lightphobes!

Easy to pick up but hard to master, Soldiers play in a first-person perspective just like your typical FPS. Soldiers will need to defend the active objective from encroaching Lightphobes and also be careful not to get killed in the process.
While AI-controlled Lightphobes (bots) may be easy to predict and defend against, things change when human players are added into the mix. Coordinate with your fellow teammates to survive together!

Playing as a Lightphobe requires a high degree of skill and patience. Being limited to melee attacks makes it difficult to kill your enemies, but the increased difficulty also makes it extra satisfying when pulled off successfully.
With their enhanced maneuverability, Lightphobes can use wall jumps to quickly scale vertical surfaces. They also have a natural invincibility in the dark, and must be exposed by a special light source before they can be killed.
If you enjoy the difficulty of sneaking up and knifing players in FPS games, then this is for you!
