Once used, the tank will emit a powerful blue shockwave which will hit any tank close to you. All tanks, dead or alive and in its range will transmit the shockwave further. Shockwave is unable to chain to other tanks if only living allies are in range. Tanks can be damaged only once by the same attack. This weapon ignores all landscape, bumpers, portals, and buffs; but can be absorbed by black holes if a player is sitting inside of a black hole.
