Molecular Gun
The Professor's own development: blobs of chemicals injure enemies and heal allies at the same time. Only Professor can explain how this happens. Unfortunately, she explains it in such a complicated way that nothing is clear anyway.
Overview
The chemical cannon fires single projectiles that explode and deal average damage for an AOE weapon, but their damage falls off slightly towards the edges of the sphere. Relative to many other guns, a fairly fast-firing gun.
Mods
Alternative mod: It is necessary to hold down the RMB for 0.8 s, after that, when the button is released, the weapon fires one, but more powerful projectile and goes to reload.
When colliding with an obstacle, it is divided into 5 small fragments, which, when falling, form a semblance of mines for a 4 seconds.
