These guns are powerful, but unpredictable, energy cannon that are crewed by Gretchin. The gun automatically hits any single model within range and line of sight. Simply pick a target and roll 2D6 to determine the strength of each hit (up to S10). If the gun rolls an 11 or 12 for its Strength it overheats, no hit is scored and one of the Gretchin is killed. Against vehicles the gun rolls its Strength on 2D6 as normal and then adds 2D6 to the Armour Penetration roll.

Errata — Chapter Approved: Codex: Orks Q&A (v1.0): When a Zzap gun is mounted on a Battlewagon, rolling an 11 or 12 for Strength has no extra effect beyond the weapon simply not firing that turn — no crew are killed, since the Battlewagon's own crew act as gunners rather than dedicated Gretchin. The "pick a target model" wording only matters when the gun is shooting at a vehicle; when firing into a squad, the squad's owner still chooses which model is removed as a casualty, as with any other shooting.
