Sentinel

Sentinel is a 2D exploration platformer set in an alternate future. After a mysterious pyramid was discovered during the 1969 moon landing, humanity shifted its focus from Earth to space. Years of research revealed a way into the monolith, but everyone who entered vanished. With volunteers dwindling, a $150 billion bounty is offered to the first person to enter and exit the pyramid. You play as a nameless bounty hunter exploring it to discover what it is.

Explore the pyramid

The game takes place across one large level with 13 unique rooms. Your Nanite Suit helps you navigate the unexplored labyrinth, and you search its rooms for upgrades that change how you move, fight and explore.

Fight and adapt

The pyramid contains five enemy types and two boss encounters. Nanite Suit abilities add new ways to approach its challenges, including vaulting off enemies and blasting through the sky. Each ability you unlock expands how you can move through the labyrinth and fight its foes.
