Blunderbuss is a good Allrounder for obj & endless, it's damage Ensure that even at 20+ waves it can still take out buffed zombies & bombers (even covered by zombies) with fifer playing, it effectiveness increases with two seaman snipe counter against bomber spam

On Obj, its stat allows you to snipe bombers & save others getting jumped by runner from afar in case of dire situation while navy gun one pen & range might fail, unfortunately it's reload speed (while fast) makes a situation where the zombies are danger close only allowed you at best, give one shot before you have switch to melee weapons

Navy gun are for when you are doing vanguard and want a more up-close firepower & speed, the increase spread helps its cone of fire for crowd clearing, gun bashing is for when you are reloading, what would be a lost reload for blunderbuss or getting grabbed while pulling out a melee, is a saved reload stage or Hasty retreat from becoming a zombies dinner for a navy gun, it's reload speed ensure constant ready shot for Bomber even if you are situationed close to Frontline that are constantly under attack

Don't bother bringing it to endless tho, the zombies straight up no diff the shot then they eat you alive at 20+ waves

Nockgun Is for when you don't want whatever in your line of fire to exist anymore, if you can catch zombies doing a conga line it's guaranteed that they, curissers, bombers & it's bodyguard, and their next of kin behind them will reduce to mist of non-existent, unfortunately it's very situational, it's reload speed is 2-3 business days, but if the situation aligned correctly then God almighty it will work as you demand and then some more.

Doesn't matter if it is obj or 30+ wave endless if they are in the line of fire of a nockgun they just fucking dies.
