We can have more weapons for the classes that don't have futuristic weapons yet.

They are weapons that, although most of the time they were not used, were fun and interesting in their own way.

weapons that reload without ammunition but in exchange reduced damage to buildings is a good idea

we already have a soldier with his
cow squeezer 5000
It has its normal attack and its charged attack that does area damage and can burn enemies in its area

the vigilante vison
gun that passes through enemies and cannot be deflected

engineer
the ponsom 6000
Their projectiles cannot be deflected
on impact -10% medic supercharge and -20% spy invisibility

pyro
the melter
normal shot that burns
secondary shuts down a teammate and deals 1 critical hit every time he shuts one down

third grade
normal ax but if you hit someone while healing with the doctor you also hurt them

phlogistonator
you can't turn off your teammates
When you deal damage, you recharge a charge when you have it at maximum, you make a taunt while being invincible and it gives you a few seconds of critical hits.
