Add Plasma Gun

Add the Plasma Gun back the gun was balanced and was used rly much and i think we should add it back and just lower the lvl 67 so the lower players to use it and it will a great addition to the game/server

Without Hawa, it was balanced and was a powerful and fun weapon, but it had a low level, and so it became unbalanced, so bring it back and raise its level to +100
