I know that you can airblast arrows from the sniper and any projectiles. I believe needles are projectiles, but I have never seen or tried to ariblast needles. Does it work?
You can't. They're just like bullets.
The following projectiles can be compression blasted:
- Rockets (Sentry Rockets, Energy Blasts, and Eyeballs)
- Grenades and cannonballs
- Baseballs and ornaments
- All liquid based projectiles.
- Arrows, healing bolts, and repair claws.
