Excavation is the first level shown off for Prodeus being available early to Kickstarter backers and in the closed beta. In the main campaign, it comes after either Genesis Part 2 or Memoriam and is followed by Marksman. It is the first level where the player gets the Grenade Launcher and can be the first level where the player encounters the Zombie Sniper, although the area with it is optional.
