Strategy
Compared to a Bullet, a Heavy Barrel offers 5% more damage at the cost of 10% speed. Since Exhaust gives the same bonus to speed that Bullet gives to damage, the Heavy Barrel does not offer a good exchange rate.

Use this upgrade on tanks where damage is essential to the exclusion of all else. Long-range tanks benefit the most from a Heavy Barrel, as the movement penalty is usually too significant on close-range tanks. But even then, it is not advisable to equip more than one Heavy upgrade onto a tank.
