The Combat Chaser is a unique weapon featured only in S.T.A.L.K.E.R.: Shadow of Chernobyl.
The Combat Chaser is a modified Chaser 13 shotgun. This model features a fragment of the Gravi artifact inserted into the barrel in such a way that it speeds up the velocity of the projectiles. As a result, the Combat Chaser is the most powerful shotgun in the game, and the most accurate. However, it is limited by a five round capacity and a pump action mechanism.
- This weapon is held by Father Diodor, who can be found at a small Loner camp in the Army Warehouses.
- Another Combat Chaser can be found in a stash in the Wild Territory, alongside a very rare Mama's Beads artifact. The stash coordinates can be picked up from any dead stalker in the Wild Territory, the Bar, or in Yantar, regardless of faction alignment.
- The fact that Father Diodor carries the weapon is very hypocritical, as he preaches the destruction of artifacts.
