surviv.io - 2D Battle Royale is a top-down 2D action game built around battles in a virtual arena. The stated objective is to eliminate opponents and become the arena’s king. Players control a protagonist across different maps, with the locations of key terrain and objects changing between games.

Changing map locations

Maps are randomly generated rather than using fixed locations. Trees, crates, rivers, and bunkers can appear in new places from one game to the next, so the layout is not the same each time. The source describes this changing arrangement as creating a different experience for each game; it does not specify placement rules or how individual locations affect combat.

Choosing a team size

Players can select Solo to go alone, Duos to battle with a partner, or Squads to play in a four-person team. These options set the stated group size for a match. The description does not detail team rules or explain how opponents are matched, so the supported choice is simply whether to enter alone, with a partner, or as part of a four-person squad.

Weapons and equipment

The available loot categories include weapons, firearms, throwables, medical items, armor, scopes, and backpacks. The description says this range lets players customize their play style, but does not explain how individual items work, how they are obtained, or whether any category has particular combat effects. It therefore supports a broad equipment choice without establishing specific item strategies.

Rotating modes and events

Alongside Solo, Duos, and Squads, the game has a daily rotation of modes and seasonal events. The rotating selection provides different ways to play, though the source does not list the modes or give their rules. Taken together, the documented choices are the match group size, the changing map layout, and the available equipment; more detailed combat or progression systems are not described.
