Combat Online 2

Combat Online 2 is NadGames' browser shooter built around online matches and player-made maps. You can switch between first-person and third-person views, fight other players, or choose challenges where movement and exploration matter more than eliminations.

Its community maps cover individual and team gunfights, parkour, zombie survival and puzzles. Pick the experience you want before joining: a shooting arena, an obstacle course and an escape-style map can have very different goals.

Combat and Challenge Maps

• Deathmatch: compete against other players individually.
• Team Deathmatch: fight alongside teammates against the opposing side.
• Parkour: clear obstacle courses by controlling movement and jump timing.
• Zombie: survive incoming waves of undead, with opportunities to play alongside others.
• Puzzle: search for routes, solve obstacles and find the exit.

Browse by category rather than judging a map only by its name or artwork. Top Rated helps you find established community creations, while Newest is useful when you want unfamiliar layouts.

Weapons and Camera Choice

The arsenal includes pistols, shotguns, sniper rifles, an RPG and close-range weapons such as a knife or bat. Match your equipment to the space you are entering: a long sightline and a tight corridor call for different approaches. Use the weapon slots to change equipment and the grenade action when the situation calls for it.

Switch camera views with F. First-person keeps your attention on the aiming view; third-person shows your character and can be useful when judging a jump or a narrow landing. Try both before committing to a difficult parkour section.

Progress and Community Creation

Eliminations, match wins and completed parkour runs contribute XP toward global rankings and unlocks. The Mods catalog also lists character models and other customization content; check an item's own requirement rather than assuming all rewards use the same progression.

The in-game Map Editor lets creators design and share arenas or challenge layouts. This is a separate creation tool, not a promise that you can place defensive walls during an ordinary gunfight.

Phone and Tablet

Use landscape orientation, the on-screen movement joystick and buttons for shooting, aiming, jumping, reloading, crouching and camera switching. Follow the current map's prompts for actions beyond these basic controls.

• Check the category before joining. A map with an unusual theme may be a puzzle or parkour course rather than a deathmatch. Knowing the goal prevents you from chasing eliminations in a challenge that rewards reaching an exit.
• Compare camera views on narrow jumps. Use third-person to see the character's position, then choose the view that makes the next landing easiest to judge. Do not change views halfway through a difficult jump while learning it.
• Learn one community map at a time. Repeat a layout long enough to recognize its routes and sightlines before hopping through Newest. That gives you a useful reference for positioning instead of encountering every corner for the first time.
• Choose equipment for your next route. Before crossing a long lane or entering a small room, select a weapon suited to that distance. A sniper's open sightline and a shotgun's close encounter are different problems.
• Give a team push more than one angle. On Team Deathmatch maps, stay close enough to support teammates without crowding the same doorway. Separate firing positions let you cover more of the player-built layout.
