FAQ
Fourth hospital, discount, HQ upgrades, VS medals, mecha — answered briefly.
The most common questions — with the way to the exact number. Missing yours? Ask the advisor; what it does not know goes on our list.
How do I get the fourth hospital?
Three steps: Special Forces research to 40 % (cheapest: 89 of 221 levels, at least 49,160 VS medals, Tech Center 22), then the “Extra Hospital” research in Defense Fortifications (Tech Center 20, 250 VS medals), then build the hospital (HQ 21). Assumption: 40 % = share of all levels.
Why are my costs lower than in the wiki?
The wiki shows base costs. Almost everyone has a cost discount (usually 5 % among members), already deducted in the game.
What do I need for the next HQ level?
The building calculator shows cost, time and requirements for any range. Or ask the advisor, e.g. “I'm HQ 22, what do I need for 26?”
What are VS medals for?
For Alliance Duel research and Special Forces research (400 to over 1,000 per level), plus a few single items such as the Extra Hospital (250).
Which day do buildings and research count in the duel?
See the week plan, day by day in server time. Finished buildings stay gift-wrapped until you tap them — only then does the power count. So finish them beforehand and open them on the right day, ideally in an arms race window “Base Buildings”.
Which heroes against the mecha?
Aircraft heroes against the red tank, infantry heroes against the red fighter jet — +50 % damage each.
