Copying my steam post since you guys might find it interesting too.

So I'm doing a heavy run for fun, and found the plasma rifle lacklustre. After a bit of digging, i found about the bug that uses multiplayer damage values for this gun. Couldn't find a simple patch for it besides big game overhauls, which I'm not interested in. After much playing around with the console commands, I figured out how to fix the gun without mods!

set plasmabolt mpdamage 40
set plasmabolt mpblastradius 128

done.

Fun facts: HitDamage and mpHitDamage are irrelevant for weapons that shoot projectiles, you have to modify the damage of the projectile itself. I was testing things with the pistol, gave it 1000 damage (it was oneshotting everything), then change it's ammo to darts and it was doing normal dart damage. Tweaked the dart damage to 1000 and it's oneshotting robots again.

Sorry if this is known, I've spent the last 3 hours looking for a simple fix and couldn't find one, so here it is.

This should also fix the pathetic plasma oneshot widget (forgot the name), but haven't tested it yet.

Just reloaded my plasma test save in Secret MJ12 Facility to test, and this thing is a completely different gun now. Extremely good and fun!
