Shields Block Stickers
Shields prevent slow effect from projectiles and pools created by spitters and worms.
If the shields break, you'll find yourself slowed as usual while you shake off that acid as they recharge.
Note
Tested locally to work with the player character, tanks, and spidertrons.
Could potentially cause issues in multiplayer servers - I'm testing this separately.
Feel free to provide feedback in case of any bugs etc.
