The fastest-killing SMG in Wardogs is the Super-45 — ranked here by measured time-to-kill across every SMG in the game, with the reasoning and the full board below. Fastest TTK, not an unqualified “best gun.”
The best SMG loadout in Wardogs right now is the Super-45. It posts the fastest measured time-to-kill of any SMG in the game -- about 210.4ms on a balanced profile, 170ms clear of the AMP-9, the next-fastest.
That order comes from scoring 5 SMGs on measured time-to-kill from community ballistics testing -- not on feel, and not on a spec sheet. The numbers come from more than one attributed data set (each weapon is tagged on the board), so compare across data sets with care.
