Every hero changes the heroes beside it. Arrange 46+ heroes on a grid, chain their abilities, and find the layout that multiplies your damage. Then prestige across 21 worlds, fight with mounts, and run missions, mines and a workshop while you're away.

Every hero changes the heroes beside itFormation Builder Idle is an idle RPG about placement. Your heroes fight on their own, but where you put them decides how hard they hit. Move one hero by a single slot and your damage can change by orders of magnitude. A puzzle made of 46 heroesEvery ability reads the grid. Some heroes buff their neighbors, some buff a whole column, and some care about traits or the entire formation. Lorn buffs every neighbor, and gets stronger for each neighbor and each different trait among them. Perrin copies the buffs aimed at him and passes them to the column in front. Nerissa gets stronger the more positional buffs point at her. Falgrim counts the traits he shares with his neighbors, and his bonus grows with the square of that count. With 17 traits, gear on every hero and a scarf stat that strengthens that hero's ability, the best layout keeps changing as your roster grows. Save several formations per world and switch between them. Left-click levels a hero. Right-click buys max. Prestige across 21 worldsPush until the waves stop you, then prestige. Your gold becomes talent points to spend across 99+ talents, and each world pays out its own World Essence. There are 125 stages to clear, and World Mastery rewards you for going back to earlier worlds with a stronger team. Mounts and the Tower of DominationThere's a second combat game inside the first. Collect 12 mounts, level them up, give them hero riders and build teams around 6 terrain elements for a 100-stage mount campaign. Then take them into the Tower of Domination, a weekly 1v1 climb where leaders don't count and only mount stats, abilities and elements decide the fight. Heroes who aren't fighting still workMissions. Send spare heroes on timed missions. The crew planner shows your success chance before you send anyone. Mines and the Workshop. Put heroes to work as miners and station workers for resources and permanent DPS bonuses that survive prestige. Pets. 13 pets that either buff a hero or go farming for Pet Treats. The Seer.

About the game · Oct 16, 2026, 5:18 AM

Previous
<h2 class="bb_tag" >Place Your Heroes. Optimize Your Formation. Conquer Every World.</h2><br>Formation Builder Idle is an idle RPG <strong>where the location of your heroes matters just as much, if not more, than which heroes you use</strong>. Drag your roster onto a tactical grid, see the impact of abilities change based on your formation, and push deeper into an ever-escalating wave system, then close the game and come back to a pile of rewards.<br><br>This isn't a game where you just stack your strongest units and walk away. Hero abilities interact based on grid position, buffs ripple outward, gold multipliers stack with DPS amplifiers, and the difference between a good formation and a great one can be orders of magnitude. Finding that perfect layout is where the magic happens.<h2 class="bb_tag" >40+ Heroes, Each With a Role to Play</h2>Every hero brings a unique ability to the grid. Some boost adjacent allies. Some multiply your gold. Some scale with the number of heroes around them. Pair that with individual gear sets, traits, and level scaling, and you've got a roster where every hero has a reason to exist, and a formation where they shine.<br><br>Left-click to level up one at a time. Right-click to buy max. Simple controls, deep decisions.<h2 class="bb_tag" >Systems That Feed Into Each Other</h2>Formation Builder Idle doesn't have one progression path, it has many, and they're all connected:<br><br><ul class="bb_ul"><li> <strong>Heroes &amp; Gear</strong>: Level 40+ heroes with unique abilities. Equip gear that boosts damage, cuts upgrade costs, speeds up missions, and strengthens your mount riders.<br></li><li> <strong>Talents</strong>: Prestige to earn talent points, then invest across 52 talents to shape your build: raw DPS, gold scaling, wave skipping, mount power, mission rewards, and more.<br></li><li> <strong>Mounts</strong>: Collect mounts with Power, Stamina, and Speed. Level them up with Animal Food, build mount teams, and assign hero riders for bonus stats. Then take them into a full mount combat system, fight enemy squads and climb the Tower of Domination.<br></li><li> <strong>Pets</strong>: Assign pets to heroes for passive bonuses. Or send them farming to earn Pet Treats, then spend treats to level them up, stronger pets, stronger bonuses.<br></li><li> <strong>Mines</strong>: Assign heroes to mine for resources and unlock permanent DPS bonuses that stick across every prestige. A worker-placement system within an idle game.<br></li><li> <strong>Missions</strong>: Send heroes on timed expeditions for bonus rewards. The right gear and talents cut the wait and boost the payoff.<br></li><li> <strong>Seer</strong>: Spend Diamonds on pulls for permanent stat bonuses that compound over time, DPS, gold, talent points, and mount combat power.</li></ul><h2 class="bb_tag" >Prestige Across 17+ Worlds</h2>When you've pushed as far as you can, prestige. Cash in your gold for talent points, earn World Essence, a unique currency for each world, and start the climb again, stronger than before. With 17+ worlds and over 100 stages, there's always another wall to break through.<h2 class="bb_tag" >Idle Done Right</h2>Close the game. Your formation keeps fighting. Come back to offline progress, gold earned, waves cleared, chests dropped, mine resources gathered. Formation Builder Idle respects your time whether you're actively playing or checking in once a day.<h2 class="bb_tag" >Mount Combat, A Game Within the Game</h2>Beyond the main wave game, there's an entire mount combat system waiting. Level up your mounts with Animal Food, assemble teams with terrain element synergies, assign hero riders for stat bonuses, and pick your team leader for an edge in battle. Fight enemy squads and climb the Tower of Domination, a multi-chapter campaign with escalating difficulty. It's a whole second layer of strategy to master.<h2 class="bb_tag" >Early Access, Built With Player Feedback</h2>Formation Builder Idle is in active Early Access development by a solo developer. New heroes, new systems, balance passes, and quality-of-life updates ship regularly. Your feedback directly shapes what comes next.<h2 class="bb_tag" >Features at a Glance</h2><ul class="bb_ul"><li> 40+ heroes with unique abilities, traits, and gear sets<br></li><li> Tactical grid-based formation building with multiple save slots per world<br></li><li> 52 talents across a deep prestige system spanning 17+ worlds<br></li><li> Mount combat system with leveling, rider bonuses, and the Tower of Domination<br></li><li> Pet farming, leveling, and hero assignment system<br></li><li> Mine worker placement for permanent cross-prestige bonuses<br></li><li> Timed missions with gear and talent optimization<br></li><li> Seer system for compounding permanent stat growth<br></li><li> Robust offline progression that respects your time<br></li><li> Available on Windows, Mac, Linux, Android, and Web<br></li><li> Competitive leaderboards</li></ul>
