Top Gun (Spitfire LMG)

is one of the many challenges in Titanfall.

This Challenge can be a little hard to do, due to the Spitfire's reversed kick pattern (High-low). That being said, it can still be very easy to kill pilots after getting used to the recoil pattern.

Tiers
There are 5 tiers. To complete the Regeneration challenge, you must reach tier 5. Tier 1: Kill 5 pilots. Tier 2: Kill 15 pilots. Tier 3: Kill 30 pilots. Tier 4: Kill 50 pilots. Tier 5: Kill 75 pilots.
