Evolve is getting some new free and paid content later this month.

The Behemoth DLC adds a new creature to the game for AU$23 (free for those who pre-ordered). Behemoth is a tank of a Monster that becomes a giant, destructive boulder and rolls through the environment for quick traversal.

Meanwhile, four new hunters will be available for AU$11.25.

They are: Torvald, a cyborg Assault character with a mortar cannon for an arm; Crow, a Trapper with a pet Batray for tracking monsters; Slim, a genetically modified combat Medic; and Sunny, a Support character equipped with a mininuke grenade launcher.

Those who own Evolve but do not purchase Behemoth or the four new Hunters can still play against or alongside these new characters online and against them offline.

As for free content, two new maps will be added, alongside an Observer Mode which allows a sixth player to spectate and live stream from the viewpoint of any player at any time.

Observer Mode includes a HUD that updates in real time throughout the match, showcasing player health, survival odds, perks, the mini-map, and more.

All the new content will be available on all platforms from March 31.
