About this game

Two heroes. One chain. A thousand skeletons. Neither of you can win alone.

Locked Together is a top-down co-op survival game built for exactly two players. Grab a friend or partner, each of you on your own phone, and fight side by side in real time. A glowing chain links your heroes and burns every enemy that crosses it, so how the two of you move together is the whole strategy.

ONE THUMB, ZERO SETUP
Drag to move. Your hero attacks automatically. Tap once for your special. No menus mid-run, no tutorials to sit through. A stage takes about four minutes, so it fits a bus ride or a coffee break.

THE CHAIN
Stretch it across a horde to cut them down. Pull it tight to protect each other. Wrap a boss between you and watch its health melt. Every wave is a conversation between two players, and the chain is how you talk.

BUILD A RUN TOGETHER
Collect XP, level up and pick from three random upgrades every time. Stack weapons like Fireball, Chain Lightning, Frost Nova and Meteor Storm with passives like Brawn, Magnet and Iron Will. Choose duo upgrades that only work when both of you commit, and evolve your weapons into something bigger. No two runs are the same.

HEROES AND PETS
Unlock a roster of heroes, each with their own weapon and special, and pair them with pets that fight alongside you. Level them up between runs, chase achievements and grow your pair level as a team.

MODES
• Co-op by invite: share a six-letter code and play with anyone, anywhere.
• Solo with a bot partner: practise or play when your friend is busy.
• Stages: fight through waves and beat the boss to unlock the next area.
• Endless Night: how many rooms can the two of you clear before dawn?
• Boss Rush: back-to-back bosses, no breathers.
• Weekly and all-time leaderboards for Endless and Boss Rush.
• Daily quests and streaks for extra rewards.

TALK WHILE YOU PLAY
Optional built-in voice chat connects you straight to your partner, and only your partner. Turn it off any time, mute with a tap, and block or report anyone who ruins the fun.

FAIR, NEVER PAY-TO-WIN
Every hero, pet and upgrade that affects your stats is earned by playing. Coins and chests come from runs, quests and streaks.

MADE FOR PHONES
Smooth 3D action tuned for mobile, with a low-graphics mode for older devices, left-handed controls, colour-blind support and haptics you can switch on or off. Sign in with Google Play Games to keep your progress across devices, or jump straight in as a guest.

Locked Together is best with someone you trust. Chain up, move as one, and see how far the two of you can go.

Requires an internet connection for co-op and leaderboards. Intended for players aged 13 and over.
