Are they even good?

Sniper is fine for me, it sadly get completely outclass after level 12 by anybody with fast weapon

• additional problem are 7AP guns on 12-13 AP character...

Melee literally don't exist for me later in the game...3+ AP for attack not gonna fly...

Heavy weapons?

• pressure cooker works nice - literally only thing i was using later in the game
• at the very end i unlocked Burning Sawblade launcher that did ok damage for 7ap
• Pistol with Toaster Repair works better for a burn effect and i m more snowball thrower

Weird Science?

• i never used science weapons as weapons, science armors and gear was fine

Explosive:

• it doesn't exist, i literally used it to disarm traps
• however i do recognize power of right rocket at the right time

my experience:

I used overpowered DLC items from Aspen

• 2 AP never reload shotgun
• 1AP meat-fist
• Crystal crossbows with 1700 crystals from dlc on 2 characters
• PDW - this one kind of make a lot of weapons looks weak

Even before Aspen some of the weapons feelt weak

• Sniper holds up as enemy deleter
• anything heavy sux

i played on non-supreme jerk difficulty

i don't mind game getting hard, i just play for fun not to reload a lot of battles

• i wanna replay the game, just don't wanna have people doing 1 shot and nothing for rest of the turn when Mr Crossbow reload 12 times and fire 12 times with range of sniper
