The EMP Cannon is a late game weapon unlocked at ship level 10. The cannon sends a barrage of EMP lasers that do decent room damage, these lasers do not damage crew. The lasers also need to be recharged with gas for use.
The EMP Cannon can be a pretty high risk high reward weapon. The weapon itself takes alot of power and does only 2-3 bars of damage to shielding. However, if you can take down the shields fast, it can heavily stun long charging rooms like the Ion Cannon and Teleport.
If your level 11, chances are all the other level 11 people have it. If your level 10 and can power and fit it, go for it, it really hurts Teleporters and the Hangar. Alot of people will try to take out EMP weapons first so make sure you armor and man this thing well. Note that the EMP Cannon is classified as a cannon in the Command Center.
When To Use
If your level 10 and in a dilemma, try to think about the following. Do you have trouble fighting boarders, do you have enough wiggle room to fit a 4x2 room without cutting off important rooms, do you have enough shield damage for it, and can you power it. If you say no to atleast two of these, you should wait till your level 11.
If your level 11, there really isn't much of a reason not to use this weapon. You should have enough crew, space, and power to fit this weapon. Unless you want to use the room for something else, the combination of this weapon and the Ion Cannon can annihilate rooms with ease.
