  • Not available in Lost Alpha.

Developer's Cut


  • Does not need to be upgraded in order to use the scope and silencer attachments.
  • Though its upgrades are expensive, this weapon can be made into one of (if not the most) accurate assault rifles in the game.
  • The PRM Weapon Pack in v1.4007 changes the weapon:
    • Silencer no longer attachable
    • Instead of the standard Warsaw Pact scopes only the PO 4x34 scope (introduced in the PRM Weapon Pack) can be attached


  • In v1.4002 the rifle is named "Tunder" 5.45, though there is already another variant with the same name (therefor the inaccurate title of this page).
