or aboard a station among the asteroid fields. Raise an army, sign an alliance, plant
your spies — and hold the relics when the era ends.

The map is alive
Every dot on the map is somebody’s plan
Fleets cross continents. Outposts spring up overnight. Radar shows you what is coming, if you built it in time. And when a rival gets too strong, there is always the silo and the ion cannon.
Choose your battlefield
Four worlds. Every one a different war.
Each world has its own map, its own army of twenty-seven units and its own
way of winning. Pick the one that fits how you fight — then pick your server.
Earth
A satellite map of our planet: eight continents and the largest map of all. Metal, oil and energy fuel infantry, vehicles and tanks.
Mars
Terraformed Mars: seven continents and little water. The smallest map, so the fighting is fast and fierce. Tanks gave way to Mechs.
Fantasy
Castles among mountains and forests. Gold builds the army, Lumber moves it, Mana powers the spells, and a castle of the fifth level breeds Dragons.
Galaxy
Space stations in sectors A1 to D8, divided by asteroid fields. Fighters, Frigates and Cruisers fuelled by Minerals and Gas.
The arsenal
108 units. Every one with a job.
Three chassis, three weapons, three upgrades, in every world. Armour holds the line, damage breaks it, range strikes first, and every weapon has a target it hits hardest.
Your base
From one farm to a fortress
Nine rows of structures, five levels each. Every level changes how your
colony looks — and what it can do.

The leaderboard
Who rules the worlds
The top ten rulers on every world. There is room at the top.
Servers
Pick your server
Every world runs on its own servers, each at its own speed and era. Join one and
found your colony — you can keep a ruler on several.
What you do
Every tick is a decision
Build an economy, field an army, make friends you can trust — and
enemies who never see you coming.
Grow your colony
Farms, mines, wells and reactors across nine rows of structures. Your workers multiply
everything the mines bring in.
Field 27 units
Three chassis, three weapons, three upgrades. Every weapon has a target it hits
hardest, and veterans level up in battle.
Claim the map
Found outposts, seize mines and wells, and raise radar posts, training bases, teleport
gates and missile silos.
Fight with allies
Alliances of up to ten rulers share radar, trade resources, mark targets on the map and
land their attacks on the same tick.
Work in the shadows
Train a spy and plant agents, then jam radars, lock down outposts and sabotage an
enemy before the battle starts.
Win the era
Ten relics drift across every world. Hold all ten for 100 ticks and your alliance wins
the era — then havoc breaks loose.

and your first outpost.

Questions
Before you pick a side
What is Battle Of World?
Battle Of World is a free, MMO-style strategy game you play in your web browser. You found a colony on one of four worlds, grow its economy, raise an army, join an alliance of up to ten rulers and fight to hold the relics that win the era.
Is Battle Of World free to play?
Yes. Creating a ruler and playing is free, and there is nothing to download. All you need is a ruler name and a password.
Can I play on my phone?
Yes. Battle Of World runs in a modern web browser on desktop, laptop, tablet and phone, with touch controls on mobile.
What are the four worlds?
Earth is a satellite map of our planet. Mars is a smaller, faster war on the red planet. Fantasy is a realm of castles and dragons, run on gold, lumber and mana. Galaxy is fought between space stations among asteroid fields. Each world has its own map and its own 27 units.
How do you win?
An era ends when one alliance holds all ten relics for 100 ticks. If nobody does, the highest-scoring alliance wins when the era runs out. Then havoc begins, and everyone fights for the fun of it.
What is a tick?
A tick is one turn of the game clock. Squads travel, structures finish, units train and resources arrive tick by tick, so timing is everything: alliances plan attacks to land on the very same tick.
Will I get attacked as soon as I start?
No. Every new colony starts with 100 ticks of protection, so you can build up first. A guided tutorial walks you through your first structures, your first squad and your first outpost.
What makes it feel like an old-school browser MMO?
The things players loved: a big map to fight over, alliance politics, spies and sabotage, nukes and ion cannons, and long rounds decided by planning rather than reflexes.
