A Level 15 Radar is required to unlock the territory containing the War Factory. Make sure that before you could even unlock this territory, you must first unlock a total of 93 other territories.
The player must beat Colonel Gearheart's level 45 War Factory in order to free her.
To unlock cpt. everspark, you must destroy a level 45 Hammerman boss base. You won't be able to locate the base until you've discovered 93 regions and have a radar of level 15, which means you won't be able to find it before you've hit HQ15. And if you discovered it today, your troops would not be able to defeat it.
For the time being, I wouldn't be too worried about it. Sgt. Bricks was a lot more supportive when I was HQ17 than Everspark is now. battle Orders skills is a fantastic game skills.
When you get there, I highly advise you to use the strategy-heavy zooka troop combo. I practically used the same tactic and it worked; I doubt I would have been able to take down the hammerbase base otherwise.
Cpt Everspark is the third hero. She is a fantastic hero who functions similarly to the electro wizard from Clash Royale. If you're new, she effectively makes an automated security retarget to the critters she spawns every few seconds. And in order to unlock her, you must first unlock a particular area in radar's top right hand corner and defeat a base. The factory of Colonerl Gearheart. You will only have her after that. Colonel Gearheart's war factory acts as a base, close to Doctor T's stages or Hammerman's islands. But it's twice as difficult.
the power to be famous Universal Remote is only accessible until Everspark has achieved level 3, which necessitates an extra HQ level. A hammerman base becomes available to battle when you update your radar (to the maximum level for HQ16 Radar 14). Everspark is unlocked after you've beat hammerman.
