Call of Duty: Modern Warfare 2

MW2’s multiplayer side in a web launcher

iw4browse focuses on multiplayer maps and modes from Modern Warfare 2. Rust is the initial map choice, and the selector also includes larger settings such as Afghan, Estate and Terminal. Free for All and Team Deathmatch are among the modes. This launcher does not present the single-player campaign.

The useful first distinction is bots versus friends. Play vs bots gives you a solo way to reach the selected arena. Play with friends leads to hosting or joining an invite, with the host’s lobby choices governing the shared session. This is a separate browser release from the native iw4L project.

Give the first load an active tab

Choose a player name, map, mode and graphics preset before starting. The current solo launcher downloads roughly 1.1 GB before the engine starts, so allow for that transfer on your connection. Keep the tab visible during loading and play. If Chrome offers Wait while the engine is working, the host asks you to let it finish.

This runtime requires WebGPU. The launcher directs unsupported browsers to current Chrome or Edge. Quality keeps sun shadows; Performance disables them. That tradeoff can reduce graphics work without changing which map you selected. Audio begins after a click.

Use the invite for a friend session

Host game creates the session route to share. Join invite is the corresponding entrance for the other players; sending a generic homepage link does not by itself join a particular host. Keep the game visible while it is running, because the launcher warns that a hidden tab stops progress.
