In Titanfall there is a challenge and an achievement:
Gooser Shoot X pilots while they are ejecting
Ejecting pilots are very quick, often cloaked, at medium to long range and always at full health (taking multiple shots with most weapons).
For some players this is easy, twitch reflexes or pure skill make it easy, but many players find it extremely hard - getting even one 'Goose' is a huge challenge.
Is there any tactic, weapon or strategy that can make this easier?
