Monster Rush: Evolution

Mission briefing

Start as a small monster on a kingdom island and grow by eating everything smaller than you: peasants, trees, rocks, houses and squads of knights. Rival monsters roam the same island — catch the smaller ones and keep away from the bigger ones. When time runs out, the largest monster on the island wins. Each time you grow, the action slows down and you choose one of three mutations. Shape a Predator, a Glutton or a Titan: 18 mutations in three branches, plus a golden apex mutation for every branch you commit to. Two rounds rarely play the same way. Collect DNA to evolve into new forms — GROKK, SKARRA, FROSTFANG and IGNIS — each with its own ability: slam, dash, roar or fire breath. Explore the kingdom map: 4 regions with 10 islands each. Every island has its own goal and three stars to earn. Stars open new regions, codex entries and star chests, and round modifiers like night, meteors or a gold rush keep every visit fresh. Features: - Arena action: eat what is smaller, avoid what is bigger, finish as the largest monster - Mutation draft: 18 mutations in 3 branches (Predator, Glutton, Titan) + 3 golden apex mutations - 4 monster forms with their own abilities: slam, dash, roar, fire breath - Kingdom map: 4 regions, 40 islands with 3 stars each, then endless islands - 6 island goals: Be the King, Siege, Feast, Hunt, Survive, Boss battle - Round modifiers that change the rules: night, meteors, gold rush, stampede and more - Castles with boulder-throwing towers and a boss monster at the end of each region - Mutation codex unlocked with stars, star chests, 20 skins, daily gift, quests and achievements

Field manual

Drag anywhere on the screen (or use WASD / arrow keys) to move. Eat anything whose number is smaller than yours. Tap the ability button or press Space to use your form's ability. When a mutation draft appears, tap a card (or press 1–3).

Launch orders: press Launch mission above and the game loads on this page itself — nothing downloads and no form stands between you and the first move. It is designed for a flexible screen and takes its orders from mouse, keyboard or touch, depending on the mission. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly. If it offers a fullscreen control, use it — a fight this size deserves the whole screen.

Field notes for .io arena operations

• Eat at the edges. The centre of an .io arena is where the giants feed; the rim is where small players grow fat on leftovers nobody bothers to chase.
• Never chase a smaller player in a straight line for long. Every second of pursuit is a second the whole arena can see, and something bigger is always watching the chase instead of the chased.
• Use your size as a rumour, not a shield. The moment you make the leaderboard, you become content for everyone's evening — spend big size on safety, position and patience.
