Hi Atholl here with new ideas.
This time i'll try to create a new type of gun with a unique kind of mechanics.

Slicer:
Clip Size: 3
Bullet Size: average (catalyzer-line/blaster-line)
Damage: average (Blaster-line)
Firing Speed: average (Blaster-line)
bullet range: average (antigua-line)
Bullet speed: very slow (catalyzer-line)
Moving while shooting : yes
Charge Time: short (Pulsar-line)

Mechanics:
Normal: The shoots froze on place on hit or by reaching the maxium distance (with a maxium of 3 bullet stopped at the same time), they will desapear once a fourth bullet is shoot or after a certain ammount of time (the bullets stops in place in the moment you fire the other).
Charge: The bullets currently present on the field will "connect" dealing almost double the damage of a normal bullet (this will refresh the time of the present bullets before desapearing)

Tell me what you think about it, and if you feel like it add some ideas too.

EDIT: edited the normal shots mechanics and the size of the bullets
EDIT2: added gun comparisons.
