Regarding E. Rabbits, headshots are necessary as well as prioritizing targets.
- Shoot the closest target to both maintain accuracy and avoid detection.
- Pick off outliers and keep movement minimal to avoid spooking others around.
- Try to find good vantage points - like a rock you can climb upon - and prepare to wait.
- Don't rush shots since you want a stationary target to accommodate flight time.
I just step away and grab a snack or play Bust Through in the meantime.
Kinda like waiting for ducks or geese to fly overhead.
Don't worry, you'll get the hang of it!
