The soldiers become trapped in the jungle, facing dinosaurs and uncovering secrets about a Brazilian Military Dictatorship biological weapons program.
The game includes a Story mode, which takes 1-3 hours to complete, an Arcade mode for quick survival matches, and both Cooperative and Competitive Multiplayer modes. A point system allows players to unlock weapons and cosmetics during solo play. The environment features a day-night cycle, weather effects, and a variety of visual and sound design elements.
