If you know the Guns & Hookers strats then this is easy enough.
MAFIA: Hide gun, claim gs was hooked. Nilla should CC unless cop outs with report on hooker. Nilla can claim trapper d2, or if you're about to get shot, remember to say you trapped people who are still alive.
TOWN: If gunned, out with gun before gs says he gunned you, this clears you. Give the cop a few seconds before you shoot on gs orders.
TRAPPER: Don't trap n1. Trap cop n2. ONLY IF COP DIDN'T OUT OR SOFT, trap a cleared town (who outed gun before gs said who he gunned). Otherwise trap the gs. Claim trapper if you're about to get shot. Check to see if cop softed d1. Out on d2 with who you trapped both nights.
COP: Out as you would in pretty much every setup. Try and soft if you have a maf report. Out if your inno report is going to get shot.
GUNSMITH: Gun anyone n1. Give town a second to out gun on d1 before you say who you gunned. The biggest change from regular Guns & Hookers, is for gs n2. Gun the trapper if he outed. If cop outed and, BOTH a clear town AND the cop are alive, gun the clear town.
