  • The Road Tunnel is slightly different now (being a bit wider and filled with more junk).
  • A new Underground Tunnel System has been added underneath the map (Starts at the Road Tunnel, stretches up to the Bridge Checkpoint and also over to the Trade Route Tunnel).
  • The Car park that the player assaults with Petruha has been replaced with the Old Factory from previous builds.
  • The Farmstead outside the Trade Route Tunnel has also been replaced with the Abandoned Shacks.

- Detailed task information

Rescue novice and retrieve the flash drive

  • The second involves finding a flash drive.
Apparently there's a rookie with valuable info for Sid, and he's in trouble. Somehow, I feel like a babysitter. Am I that old or what?
- Detailed task information

Find the second contact

  • The third involves clearing out a gang of Bandits and finding another flash drive.
There was another contact of Sid's that didn't make it. Sid told me his body at the bandit camp in the factory. The rookie village's leader, Wolf, should help me in clearing out the thugs.

Save Fox

  • The fourth involves liberating the local Technician.
These strange Sin fellows seem to have a bone to pick with Sid. One of Sid's contacts, Fox, is being held hostage. Guess who has to play the diplomat? Another babysitting job... Great.
- Detailed task information

Meet with Seriy.

  1. Learn something of Strelok from Seriy.
  • A man named Seriy, located up at the Hangar in Garbage, knows some information on Strelok. Head back up to the road from the Rookie Village (or the Sin House if the player chose not to go back to Sidorovich), and proceed north up the road until a small military checkpoint is found.
  • If the player sticks to what the military says, they will be allowed to walk into the next level unharmed. Keep to road and walk up through the doors till the military contacts the player again, leaving them free to enter Garbage.

(Refer to Garbage for the next part of the storyline section).

All versions:
  • A strange, half translucent anomaly can be found just off to the left of Sidorovich's bunker (in the swamp area). The anomaly generally sits in place until either shot or walked into (where upon it will jump into the air then fall back down). Upon walking into it, the player will be hit with the Bleeding effect and is unable to stop it. See Grabber for history and details.
  • A lone Bloodsucker will spawn in the same swamp area as this anomaly (may sometimes be found dead laying beside it)
