Sniper (Fallout)

Sniper is a perk in Fallout, Fallout 2 and Fallout Tactics.

Effects
With this perk, any successful hit in combat with a ranged weapon will be upgraded to a critical hit if also passing a Luck roll: essentially, the critical hit chance is Luck * 10%. If that roll fails, one may still score a critical hit according to the usual probabilities.

Bugs
In Fallout Tactics, version 1.27 does not produce the advertised result of the Sniper perk. The perk is obtainable, but is bugged (tests with 10 LK have failed to produce any noticeable increase in critical strike rate, which should produce a 100% critical strike rate). This can be fixed by hex-editing bos.exe - change 4C to 6C in the address 004A6C4C.
 * Even with the fix, the perk has been reported to only work with long-range weapons such as sniper rifles or laser rifles.
