I did run out of ammo once without dying. With an XL engine, I doubt that will happen often. Feel free to exchange the TC for more ammo. Weapon Groups 1. 2xAC5s, Left arm RACs. 2. 2xAC5s, Right arm RACs 3. Left Arm 4. AC5s 5. Right Arm 6. 2xAC5s, 3xRAC2s (25+ dps, no ghost heat) Start out by squeezing down on Weapon Groups 1 and 2 until you get to about 70% heat. Then switch between WG 1 and 2.
