Poison Arrow is a heavy amphibious tank with thick armor and a powerful AoE plasma cannon. Too expensive and slow to use alone, its niche lies instead in easily killing groups of units sent to counter amphibious assaults. In essence, it is an upgraded Pounder with much greater range and speed—yet it is still quite vulnerable to T2 skirmishers and assault tanks.

As an amphibious tank, it can climb hills just as well as bots can, letting it strike from unexpected angles.

Combine with other amphibious tanks and support units that can follow them underwater, such as Trashers/Manticores for anti-air coverage and Muskrats to repair units and reclaim wrecks.
