It used to shoot out of both barrels at the same time. If people chose to spam Cougars it could get a little laggy. We wanted to keep the fast rate of fire. We ended up doubling projectile damage and making the Cougar alternate barrels. We get the same result, it retains the same feel, and you half the amount of projectiles and fix the lag issue. Now the problem is that effects don't support alternating barrels. We can only choose between no muzzle flashes, or muzzle flashes on both barrels. I found that although the Cougar looks a little underwhelming without muzzle flashes, it looks significantly worse with an overload of muzzle flashes.
