O-Canon2 (alternatively Omega-Cannon2) is a powerful Program Advance that is fairly simple to construct. One of the easiest to put together, O-Canon2 is made up of five consecutive HiCannon chips. While not as powerful as O-Canon3, it does far more damage than O-Canon1. Just as with the other Advances in the Omega series, O-Canon2 allows use of the constructing chip (in this case HiCannon) for a full 10 seconds. O-Canon2 acts exactly like the other chips in the Cannon family: the first enemy in the line of fire is hit, in this case for 80 damage apiece.
