The Surge released a DLC earlier this week. It adds a new area to the game, CREO-World, which is a theme park for the CREO workers to relax and have fun.
To celebrate, the Steam version has been on sale (ends Thursday at noon EST I think).
You can get the base game for $20 or game + DLC for $40 (5 bucks off the full price of DLC). If you enjoy Dark Souls or Bloodborne then I certainly recommend this game. It is fast-paced and aggressive like Bloodborne and the combat system is nifty.
