Base gun = 15 damage / Low fire rate
level1 3.000$ = 12 damage / Good fire rate
level2 5.000$ = 16 damage / Insane fire rate
level3 6.000$ = X16 damage / Low fire rate
The level 2 and 3 are almost equal when you compare the fire rate and the damage…
So i never buy the 6.000$ upgrade, seems useless. But maybe with a damage upgrade…
What do you think?
