Sanseong: Fortress Defense

Co-op random tower defense

Free · Designed for iPad. Not verified for macOS.

Monsters came down the mountains one night. Two commanders hold one fortress back to back. Alone, an AI commander takes the other side. Joseon, the night the monsters came down the mountains. Two commanders hold one fortress back to back. - CO-OP RANDOM DEFENSE: draft archers, fire carts, rocket launchers, warrior monks, shamans and exorcists. Merge three of a kind to rank up. Monsters you miss cross over to your partner's lane. - SOLO OR TOGETHER: solo with an AI partner, quick co-op (AI if nobody is found in 20 seconds), or invite a friend. - BAD LUCK METER: every bad draw fills it; when full, your next draft is one grade higher. Turn it into a talisman and send luck to your partner. - THREE SIGNALS: "Help me", "I've got this side", "Boss incoming". Coordinate without chat. - WEEKLY TRIALS AND RETAKES: new rules every week; win back a fallen fortress within a day. The shop sells cosmetics and ad removal only, never stats. Contains ads; rewarded ads only when you choose. The game text is in Korean. Support: https://hyperity-games.web.app/support.html
