Veil canisters appear in 2009 game Wolfenstein. When shot, they negate gravity on surrounding enemies, causing them to fly into the air, incapacitated for some time. Players themselves can be affected, but being able to fire back and move freely. The canister can be placed or thrown as trap, shoot it while foes are closing by will make them easy prey. By using the canister, B.J. can instantly refill his Veil gauge.
