Barrage

 

"The Barrage will deal massive damage to buildings and units in the target area. Be careful of friendly fire! The Barrage can damage your own units."

Summary

• Barrage is the 5th weapon available for the Gunboat, unlocked at at Headquarters level 10.
• Barrage fires a salvo of 15 projectiles randomly in a 3-tile radius around the target point, damaging all Troops/Buildings and setting off all Mines, Boom Mines, and Shock Mines on hit.
• Each use costs 6 more Gunboat Energy than the previous, with a starting cost of 10 Gunboat Energy

Offensive Strategy

• Barrage has a variety of uses. It can clear numerous Mines, Boom Mines, or Shock Mines, and can also deal heavy damage to clustered buildings.
  • In terms of countering Mines, Barrage competes with Critters due to the latter's lower energy demands and more predictable projectile behavior, but still isn't fully outclassed if the Mines are close to buildings or if Critters are needed for another purpose.
  • While Artillery tends to perform better for taking out singular threats, aiming a properly centered Barrage can be another viable answer, as most of the projectiles will usually catch it, not to mention other potential targets as extra gravy. Buildings placed near the edge of the map should still be tackled by Artillery, as Barrage projectiles may land out of bounds, reducing its total damage.
    • This is indeed applicable to 7x7 buildings like Power Cores and Mega Cores, which will endure its full brunt of fire. Nevertheless, this is of questionable effectiveness as both tend to be backed by Ice Statues that significantly improve their health, to the point where Barrages will barely scratch them.

Defensive Strategy

• Apart from a Sky Shield, proper building spacing is the only line of defense against Barrage.

Upgrade Differences

• There are no visual differences between upgrades. However, damage increases (by 8-10%) with each level.

Trivia

• Surprisingly, individual Barrage projectiles deal less damage than Artillery, yet possess a larger splash radius, presumably to compensate for its inaccuracy. 
• Barrage and Rocket Launcher share their projectile models.
