HITMAN 2 – Siberia (The Prison) is a brand new addition to the Sniper Assassin game mode and can be played either solo as Agent 47 or in online co-op as either Stone or Knight; two new operatives available exclusively in the Sniper Assassin mode.
The new map will be available to download on Steam for Expansion Pass owners starting at 17:00 UTC on July 30th.
Agent 47’s latest long-range mission takes him to one of the harshest climates on the planet, where he must eliminate two targets and start a prison riot to cover his tracks.
The map is packed full of opportunities, gameplay moments and hidden secrets to explore. Some of these will also be included in the game’s challenges, which are the key to an improved score and improving Agent 47’s rifle. Each challenge that the player completes will award them with a permanent score modifier that increases their overall score, which in turn will progress their mastery with the ICA Druzhina 34 Arctic Sniper Rifle; Agent 47’s weapon of choice for this assignment.
Reaching the highest mastery level with this rifle will permanently unlock it for use within all sandbox locations within HITMAN 2.
