Hammer Knight

An action game that blends hack-and-slash with the survivor genre. Basic attacks fire automatically while you move, using Smash and Dash to send hordes of shadow soldiers flying. Enemies knocked into other enemies go down in chains, and exploding shadows blow up everything around them. The crimson fog chases you from behind, so keep moving and break through to the goal.

Characters

Mira, Lulu, Bor and Hajin each have a story of their own. Pick a character when the prologue ends or with the Hero button on the adventure map to start their story. Joining-up stages (small arenas where you hold out) have just one map → Character stories

Growth system

In-run growth — pick 1 of 3 cards on level-up

Defeat enemies to level up, then choose one of three cards. Raise a weapon together with its paired upgrade and it evolves on the spot: Spinning Saw + Quick Wrist → Blazing Saw Storm, Falling Anvil + Sturdy Hammer → Anvil Barrage, Long Handle Lv3 → Whirlwind Hammer.

Permanent growth — Knight level · Gear · Forge

Growth that stays after each run. Every Knight level raises your HP and attack, and your outfit changes from Apprentice Apron → Leather Armor → Steel Breastplate → Knight Order Armor → Golden Regalia. Hammers dropped by bosses and treasure chests change your starting weapon by type, and you can upgrade them up to +10 with gold at the Forge.

Choosing a map — 10 per stage

Every stage has 10 maps. Tap a stage on the Adventure Map and a Map row appears in the panel below. Pick a map with ◀ ▶, or press 🎲 Random for a different map every time. The preview shows the route from the start (green) to the goal (yellow), plus where the citizens (white dots), chests and nests are.

• A stage you haven't cleared yet starts on the Original Map. Once you clear it, it's set to Random unless you pick a map.
• On every map the number of citizens, chests, nests and enemy packs is the same, and so are the star goals. A citizen who was in a dead end on the original map is tucked away somewhere remote on the new one too.
• In boss and defense stages the battleground stays as it was; only the road there changes.
• The more winding the map, the slower the red fog follows. A maze won't make you any easier for the fog to catch.
• If you lose to a boss and choose Retry from boss, you fight again on the same map. Duels and co-op always use the Original Map so everyone plays under the same conditions.

Duel a friend

Press Duel a Friend on the title screen to play the Fountain Plaza as a score duel. Everyone starts under the same conditions (Knight Lv 1 · basic hammer), so even a friend who just started can win on skill. Duels don't affect your adventure records, gear, or gold.

• Score: 10 pts per kill · 300 pts per citizen rescued · max combo ×5 · clear 2000 pts + HP left (up to 1000 pts) + fast-clear bonus (20 pts for every second under 90s)
• When you finish, use Send a challenge to share a link via WhatsApp, LINE, Telegram, and more. Friends who open the link play the same stage right away and compare results on the results screen.
• Daily Duel: a new stage opens every day at midnight Korea time (KST, UTC+9), and everyone competes on the same stage that day. Scores go on the ranking, and you can see today's and this week's standings on the home page.
• No login needed. Your nickname and best score are saved on this device, and Daily Duel scores are also saved on the ranking server (delete them anytime with "Erase my server records" on the duel screen).

Live co-op with a friend

On the title screen, choose Co-op with a Friend (Live), pick a stage, create a room, and send the invite link via chat. Your friend joins instantly — no install or login — as the archer Mira, while the host plays Leon, and you fight together on the same screen. For your friend, the Smash button fires a fan volley and the Dash button rolls. If Mira goes down, have Leon stand beside her to help her up.

Tips

• Always rescue citizens. Blacksmiths boost your attack, herbalists heal you, and hunters provide covering fire — and each citizen following you raises your attack by 5%. They affect the ending, too.
• Red zones are attack warnings. Bosses show a red zone one second before they attack, so step out of it.
• Break fog armor with Smash. When the armor breaks, the boss is stunned briefly and takes big damage.
• Stuck? Retry from the boss. If you lose to a boss, you can restart right in front of it instead of walking the whole way again. The boss gets a little weaker each time you lose.
• Getting lost? Try an easy map. Star challenges that ask you to rescue every citizen are much easier on Open Field or Flat Path. Once you're used to it, take on the Maze.
• 3 stars means: clear · rescue all citizens · 50%+ HP. Rescuing every citizen can also unlock hidden stages.

Endings

There are three endings. The outcome depends on your choice in the final chapter, how many citizens you saved in Chapters 1–5, and how often your allies went down. To see the true ending, save as many citizens as you can and protect your allies.
