>>713297830Best weapon is the Sonic Boom found in the meadows underwater near the lakes and willow trees between the castle and the volcano.
It has medium-high DPS, low ammo consumption, and insane area of effect. It pretty much ruined the game how strong it is, difficult boss battles like several brat bots were easily cheesed by only focusing on dodging and just aiming in the general direction of enemies. Only downsides are slow projectile speed for speedy far distance enemies, and it lacks the minigun's insane DPS.
Best gadget IMO would be the supply drop for HP/ammo pickups and the juggernaut for tanking bosses and taking less damage in general. Anything that sustains is good. Careful that the juggernaut causes a blackscreen when entering cutscenes.
Best potion is the restoration one. If you want to cheat you can spam click it when using it to get the immediate HP buff several times.
Best outfit is the punky for lewd and red coat for cute.
