How to play Combat Online

Choose a mode (Free For All, Team Battle or Capture the Flag) and a map. Spawn, find your opponents and fight. Eliminations and objectives earn points and experience that unlock new weapons. In the map editor you can build your own arena and share it, which is also a great way to learn how good maps flow.

For your first session, start with Free For All on an official map. It is the simplest mode, and it gives you time to learn the controls, the main routes and the strengths of the starting weapon. Once you are comfortable, try Team Battle and Capture the Flag, where teamwork and objective play matter more than individual kills. After a few matches, open the map editor to see how arenas are built.

Controls

W A S D: move, Space: jump, Shift: sprint
Mouse: aim and fire, right click: scope
R: reload, number keys: switch weapon
Touch screens: aiming and moving together needs a mouse and keyboard, so a computer is recommended

Modes, maps and the editor

Combat Online offers three classic modes: Free For All, Team Battle and Capture the Flag. Each one changes the priorities of a match, from pure eliminations to teamwork around an objective. You can play official arenas or maps created by other players, which keeps matches varied. Points and experience earned in matches unlock new weapons, giving you more options over time. The map editor is the feature that makes Combat Online stand out: you can build your own arena, share it and see how other players use it, which is also a great way to understand what makes a map fun.

Winning habits

In Capture the Flag, protect whoever carries the flag: follow them instead of chasing kills. At long range, tap-fire instead of spraying for better accuracy. And in every mode, learn two or three good positions on each map, because the same fights happen in the same places.
