I probably could've done this whole run melee and pipebomb only if it weren't for encounter 5. Rare that Infected are the hardest encounter on the board but Restaurant can be fucked up late game. Almost got overrun but the shivs came in clutch again. Encounter 3 was an easy all headshots but even with time slows on headshots shamblers still suck. Seraphite Elite is just a free win after the 5th encounter.
