What causes an enethe pilot to appear on the minimap

There are a couple of options available for you:

1. First one being: Embark out of your Titan and quickly shoot the enemy pilot down. Usually greedy, enemy pilots will try their best to eliminate your Titan for their own gain, giving you opportunity to shoot the enemy down and embark back to your Titan.

2. If possible: Be surrounded with your friends and teammates. Usually when looking at your Titan's back, the viewer can notice the enemy on top of your Titan. This is especially useful if you're on a party or have your mic to communicate with. Yell out to your teammates to eliminate the enemy rodeoing on you.

3. Unlocked at level 13: Use the Electric Smoke tactical ability. Creates a cloud form around your Titan, which generates electricity and hurts those held within the cloud's radius. Rodeoing pilots, if held on to your Titan and within the electric cloud, will most likely die in this process.

4. Unlocked at level 24: Use Cluster Rocket/Missile ordnance. When used, it spreads rockets that injure and should eliminate the enemy on top of your Titan. However, shoot at a nearby wall/obstacle/enemy, so the clusters of missile could spread wide enough to hit the enemy on your Titan.

These tags show what "Generation" the player has achieved in the game, which is done by leveling up to level 50 and completing specific challenges for each generation, then "regenerating" back to level 1.
