we can make railguns, though making flamethrowers is impossible

the dev literally added 2 new weapons last update (read patch notes) a laser gun and a gun that launches shockwave bullets. @cookie, u can: use the effect part (under activated parts) set it to smoke4 or smoke2, set the colour offset's red to 4 and yellow to 2, blue to -1 (play around with it) and set explosion damage, size and force to the max. (also set particle amount and part strength to max and max speed to 10-20 but those are obvious)

If you're bored you could buy and play Besieged (it's often on sale and also very cheap). It's not exactly the same as this one but there's a great focus on building machines to destroy things and it's very satisfying when you manage to build something that works really well.

btw yall i already tried that stuff and it isnt as fun im just waiting for new updates, mainly weapons
