Kingdom: Classic

For this achievement, you need to finish the game no later than Day 25.

To finish the game, you need to destroy the four portals on your map and then survive a huge invasion battle which happens right after the last portal is destroyed.

As of version 1.20, unlocking the Day 25 achievement also unlocks Day 30, 35 and 40 achievements!

Some tips:

• Dont clear the trees directly to the left and right of vagrant camps, you want to hire at least 4 units per day, 6 would be ideal.

• Dont rush the encampment upgrades, you'll get less taxes, upgrade to stone around Day 12 or when you have 2 farms going.

• After you destroy the 3rd portal, your attack team will get massacred by the counterattack, make sure you have good defenses back home.

• Its kinda obvious but, finish off the two portals on one side, then do the other side.

• Activate the archer statue before attacking a portal, Activate the builder statue against the 3rd portal counterattack and the final one.

• Do not build towers unless you plan to defend that spot until the end of the game, towers take away archers from your main force.

• Have two builders for your catapults, 4 for wall repairs, thats 6 at least on each side, if you can.

• Remember to give your knights gold coins so they can last longer.

Quit and Save before giving the final attack order (at the border), so when the game ends, you can continue from there and try for the 100 day achievement.

All in all, good luck!
