Shock

Overview
Shock (also named "Prism" in the mobile game) is a weapon which fires a constant beam of electricity. It deals moderate damage, being able to quickly kill weaker enemies but struggling against high level enemies such as the Self Destruction, Laser, Rocket and Railgun tanks, Bosses and Turrets. It also uses a lot of ammo.

Shock however has a trick up its sleeve; it can hit multiple objects. The electricity will arc between several objects, allowing you to hit multiple enemies simultaneously. It does less damage to the other objects, but this ability still grants a nice damage boost.

Group killing
Where the are many enemies present, such as a spawner, use Shock to damage several of them, allowing you to take out groups of enemies. In later levels the increasing number of enemies makes this ability ever more useful.

Sniping
While not perfect for this strategy, range killing is possible with Shock. This works against weaker enemies but against the aforementioned stronger enemies it is better to use another turret.

Conclusion
While not the best weapon, Shock is still a reasonable weapon which is decently capable and fun to use. Go ohm, give it a shot. It might surprise you with its power.Призма
