Gas Cannon

"Gas Cannon can slowly wither away an enemy team!" In-game description

The Gas Cannon is the default slot 1 weapon for Medic that shoots grenades that explode into gas fumes, which deal damage each second based on a percentage of an enemy's max HP, for 4 seconds. Gas fumes can linger onto parts and damage enemies that touch them.

The Gas Cannon is a mostly dark gray colored weapon. It has a bulky appearance but a very thin stock, and a black colored grip. Its barrel has light green colored tubes, where the gas grenades are stored. Gas appears in a dull green color, and have very messy particles. Smaller, team colored circles can also be seen alongside the gas.

Tactics

 * Just like the grenade launcher, the grenades could explode upon impact of hitting an enemy. The explosions could deal damage, which helps in killing enemies faster.
 * The explosion can also be used to destroy non-humanoid targets.


 * Try to explode the grenades in parts such as the midpoint in Glass Houses to make use of its lingering effect. This acts as an effective area denial and could help you know where enemies are if you observe their hit indicators.


 * Gas Cannon is not an effective killer, but it could prevent enemies from healing themselves, which greatly aids your team in killing them easier.


 * Due to its long reload, only reload when you are sure that no enemies are nearby and no teammates are in immediate need of help.

Trivia
The Gas Cannon can deal up to 22.5 damage per tick, if the enemy affected by it is a Shielder with riot gear.
