From version 1.4005 Technicians require data for upgrading armor and weapons. The data are in form of flash drives or as txt documents in working computers (you need Xray PDA Downloads module to download them).

Admin Notice
This page is being used to collect the specifics on the various u/gs required by the Technicians to open their various capabilities. Some ground rules in this are necessary:
  1. The wiki is documenting v1.4005 (currently) and only finds accessible in this unmodified version should be posted.
  2. There are currently over 70 bugs reported with v1.4005 of varying levels of "bugginess" being reported on GSC forums: Lost Alpha Bugs without modpacks..
  3. Because of this state of affairs, further discoveries made with, or references to, third party modpacks should expressly not be entered into the wiki at this time.
  4. Contributors are of course free to blog about such modpack matters, or enter the data on the modpack's wiki (if extant)
  5. The logic for the above restriction should be obvious to all. Byte Me 11 01 2018 06:36CET


3-round burst for pistols (upg_info_burst_3x_nm before v1.4007) Edit

  • The Green House in Garbage where Bes and his team resides after the player takes out the sniper on the bridge is another data location. Before v1.4007 the upgrade flash drive rests in the chimney of that house, in v1.4007 it is in the table next to the AK of the doomed one)

Restoration system schematicsEdit

  • Is on a flashdrive in the Countryside tunnels. After reaching bottom of the elevator shaft and stepping in, above the player's head is a platform with a defective ladder. There is a flash drive located on the derelict control gear. The ladder is bugged in all versions of the game, but it is possible to get up using low crouch and a 'weave' at the top of the ladder. It's also possible to push out the flashdrive with grenades. If the trick with crouch and weave would not work, it's also possible to use the "ph_gravity x" console command (my suggestion is 4 as value for x) and simply jump up to the platform.
  • (v1.4007) Moved into the tunnel of Water Dam, in a room just before the cut-scene. Its on top of the only wooden desk.
