Battle Royale is the fifth game mode (and first by Miniclip) added to the browser version of Agar.io. Across all platforms, Battle Royale is the 6th game mode added to Agar.io overall. The mobile exclusive Rush Mode is the last mode added. Battle Royale was released in May 2018 for browser and in March 2019 for mobile devices. Winning a battle royale match is awarded with a battle potion.
In early April 2018, an announcement photo was posted on Agar.io's official Facebook page. Its moto was : "Can you survive the battleground?" Battle Royale was officially released about a month later. In March 2019, Battle Royale was added to mobile editions. It is currently one of three gamemodes for the platform, the two others being Classic and Rush.
This game mode follows the basic Battle Royale format used in many first-person shooter (FPS) games. The arena will shrink at set intervals with only one winner at the end. A player loses the match when eaten (by a cell or spawner) or by staying outside the safe zone for too long. Battle Royale uses the same arena and mechanics as Experimental Mode. To maintain balance, this is the only game mode that does not allow Mass Boosts.
Battle Royale has two phases: Warm-up (Pre-match) and Battle. During the warm-up phase, players can explore the arena while waiting for the match to begin. Players can see, but not interact with other cells, pellets or viruses at this time. The match will begin once at least 20 players join the arena. The location of each player is also reset as the match begins.
- At the very beginning, focus on getting mass by collecting pellets. It might be smart to look for spawners (mother cells) in the warm up phase and then to go to them after the start, if any are nearby.
- As soon as you gained more than 132 mass, move over a virus to eat it.
- But in general, always prefer to eat spawners, because they will add more mass (250). You need about 300 mass to eat a spawner.
- When split in more than one piece, you may feed all but one pieces to a spawner. Then eat the spawned pellets. This might save time in comparison to wait for the merging of the cells. However, there is a risk of another, bigger player trying to eat the ejected pellets.
- In general, "economy" is key in the early and mid game. Therefore, focus more on eating viruses and spawners than splitting a lot to eat opponent players. Remember that viruses do not poison you when you are split in 16 pieces.
- Shooting viruses against other players usually costs a lot of mass and therefore should be avoided and only used when it is worth the mass loss
- In the end game, avoid splitting, as the merging needs a long time when you are big.
- In the end game, if some player is bigger than you, you can try to team with smaller players and they can help you to eat bigger one.
- If - during the final stage - there is you and another big cell of similiar size, make sure you are exactly in the center of the save area when the size of the area decreases. The opponent cell will be hit by the danger zone earlier and explode. The pieces of the opponent will feed you and you will eat the opponent.
