Brutal Warfare: After Effect
In Camalex97's Brutal Warfare: After Effect, This has a 8 shell slot, a slow rate of fire, and about 150 pellets (random number around that) come out of each shell but have a large spread so close combat is better with this shotgun and also more reliable that the other shotguns. When Pack-A-Punched it becomes the "REAPER" gaining 25 rounds total, 50 more spare ammo, incendiary rounds, five shell reload, and a auto feature which can be selected by double tapping Y in Xbox and the square button on PS3.
Time Travel Will Tell/Dawn of a new Dusk
The KS-23 replaces the Olympia as the 'wall shotgun' from L'Étranger onwards. It has moderate damage, which is roughly 50% of that of the Trench Gun. When Pack-A-Punched it becomes the Kill Shotinator, reloading all shells at once, becomes semi-automatic and gains Dragon's breath shots. It has appeared in the following maps:
- Wald des Todes
- Den Endkampf
- Sacrificial Night
- Concurrent Demise (Rounds 1-10, 21-30 etc.)
- Lament of the Dead
- Shinin no meiyo (switches with the Sawed Off Double Barreled every round)
The KS-23 will appear in an upcoming project of 900bv's.
