Build with your engineers, raise an army in your factories, then drag, right-click and break the enemy's petals. Played in the game itself, with its HUD, at its highest detail.
Petalwar: real-time strategy with tanks, aircraft and fleets. Every base grows around a Heartbloom, guarded by five petals. Break the enemy's petals, then bring down their bloom.
To build, select your engineers, pick a structure, and click to place it. Extractors mine matter. Generators make energy.
Select a factory and click a unit to queue it. Shift-click queues five. Tanks for the ground, aircraft for the skies, and fleets for the river.
To attack, drag a box around your army, then right-click a target. Artillery outranges defences, anti-air guards the sky, and shields cover the line. When the last petal falls, their Heartbloom lies exposed. Strike it down to win.
Climb the tiers for heavier armour, shield domes and missile silos. Three factions, each with its own army. Play the campaign, skirmish the AI, or battle your friends: up to eight commanders in one valley.
Guard the petals. Protect the bloom.
How a match is won
Objectives · guard · break · bring it down
Every base grows around a Heartbloom on its centre pad, with five petals standing thirty metres out. While any one of them stands, the Heartbloom takes no damage, and units will not even target it.

Explore the gallerySkirmish
Single player · against the AI · four temperaments
The AI plays by the same rules you do. It claims deposits, builds power when production needs it, upgrades one factory at a time and attacks in waves that grow to forty. And it waits for your first order, so you can look around and build in peace.
Small waves, sent early, and now and then a strike at your most outlying extractor.
Point defence from two and a half minutes, up to eleven turrets, then bigger waves, later.
A greedy economy: far deposits first, more engineers, tech sooner.
A little of everything, and no obvious weakness to lean on.
Every opponent's form drifts during the match: a sharp one has sloppy spells and a sloppy one sharp spells, so the same trick rarely works twice.
Play it your way
Multiplayer · online or LAN · up to eight commanders
Play Together connects commanders online or on your local network, up to eight on Petal Crown. Host a match, share the invite code, and meet in the valley; any open seat can go to the AI. Or take on the AI alone, pause with P and set the game speed from half to triple.
Controls that strategy players know by heart, every one of them rebindable:
On a MacBook, a two-finger swipe or a right-drag pans and a pinch zooms. Your first start opens a short voiced tutorial that shows you how.
Free beta · ready for launch
Petalwar is out for Windows and macOS, with Linux to follow. It may still have bugs, so please report them to us on mssgs.
Questions
The beta · the platforms · the game
Yes. Petalwar is in beta: download it for Windows or macOS from this page, and the game's title screen offers a newer version when there is one. It may still have bugs, so please report them to us on mssgs.
Windows and macOS now, and Linux to follow. Petalwar is built in Unreal Engine 5 for the desktop, with a mouse or a trackpad; on a Mac it runs on Apple silicon.
The heart of every base: a great crystal flower on the centre pad, with five petals standing thirty metres out. While any petal stands, the Heartbloom cannot be harmed. A match is lost only when a Heartbloom falls, and in a team match or a free-for-all a fallen side can still come back: three petal shards carried home by its engineers regrow it.
Yes. The campaign takes you through eight levels, and a skirmish pits you against the built-in AI, which waits for your first order before it starts. Every opponent is drawn with its own personality, raider, turtle, boomer or balanced, and its own good and bad spells.
Yes, since 0.5.20: eight levels played in order, each opening more of the game. The first is the economy and tier-1 tanks against a slow opponent on Hearthland Basin; then come defences, tech 2, the air, the water and tech 3, and at the end two and three opponents at once. Each level has three objectives and up to three blooms to earn, and winning one opens the next. Campaign matches are not rated on the highscores.
Yes. Your first start opens a short voiced tutorial on Hearthland Basin: a narrator shows you how to look around the valley, zoom, select your engineers and send them with a right-click, and each step waits until you have done it. Skip it whenever you like, and play it again from the title screen's Tutorial row. The guide's tutorial page shows every step.
Because there was no Supreme Commander for the Mac, and because real-time strategy deserves more players than the few of us who have played it for years. Petalwar keeps the big-picture command of Supreme Commander, makes the first hour gentler, and lets friends command one base together, so a new player can learn one job at a time next to someone who already knows the way. The About page tells the whole story.
Yes. Play Together connects commanders online or on your local network: one player hosts a match and shares its invite code, the others join and each picks a faction. Maps seat from two, as Hearthland Basin does, to eight on Petal Crown (the guide’s Maps and Skirmish AI chapter gives every map’s seats), and the AI can take any open seat.
Yes. In a match of more commanders, two to four people can share one start (split command): one runs the economy and the engineers, another leads the army at the front, a third takes the air or the sea. You share the base and its Heartbloom, and every one of you earns the match's result and experience in full, on the Teams or Co-op highscores. It is the easiest way to bring a friend into their first strategy game.
It should: Petalwar started because there was no Supreme Commander or Forged Alliance for the Mac. Box select, right-click orders, attack-move on Q, Shift-queued orders, engineers that assist, control groups on Ctrl+1 to 9, adjacency bonuses and a strategic zoom with icons, around a simpler objective: guard your Heartbloom's five petals. Every key can be rebound in Options.
Yes. Petalwar is built in Unreal Engine 5 to run natively on Mac, Windows and Linux, with no emulation or compatibility layer. The Mac build is for Apple silicon, beside the Windows build, and the Linux build follows.
