Q: Can I use my Steam copy of Modern Warfare 2 to play IW4x?
A: You must use a Steam copy of MW2 to play IW4x. Read the Install Guide to learn how to use your Steam copy.
Q: On IW4x, can I play with players on Steam or Steam players play with me?
A: IW4x is entirely separate from Steam MW2 services, so it is not possible to play with people playing on the Steam version of MW2. You can, however, invite your Steam MW2 friends to install IW4x, and then you’ll be able to play together.
Q: How do I play with bots?
A: Using the console, you can spawn test clients. These are dumb bots lacking any AI and do not move. The command to spawn these test clients is /spawnBot 17 (The number is the amount you wish to spawn). The alternative is to use a bot mod such as Bot-Warfare. This will give the bots pathing and AI making them perfect for an offline match. Lastly, you can create a GSC script and use the function AddTestClient to manually spawn a test client.
Q: Will IW4x get me VAC banned?
A: The short answer is no. IW4x is completely external to Steam and Steam Servers (You don’t play with Steam users). It’s impossible to get VAC banned. IW4x players only play with fellow IW4x players as the servers are completely separate from Steam. You are at no risk of receiving a VAC ban.
Q: Is IW4x full of cheaters?
A: Absolutely not! IW4x has far fewer cheaters than Steam servers. Furthermore, server owners have full moderation control unlike Steam as explained below. If cheaters slip through, they can be quickly banned.
Q: Does my Steam rank and stats carry over to IW4x?
A: No. When you start IW4x, you will be starting at level 1. As stated above, IW4x is external from Steam, so you will have a separate rank, classes, title etc. When, and if, you go back to Steam MW2 you will still have the same rank you had before. IW4x does not alter this at all. However, you can always manually set your rank back to the level you were if you wish as this is allowed, or just use the unlock all button in the barracks menu to get 10th prestige level 70 with everything unlocked.
Q: How do I set a custom prestige and level?
A: To set a custom prestige, open the console by pressing the tilde key (~) and type the following: \setplayerdata prestige x. You can set your prestige to be 0 through 11. The console command for setting a custom level is: \setplayerdata experience x. A list of the various “experiences” for all the levels can be found here.
Q: How do I change my sensitivity?
A: You can change your sensitivity either through the options menu in-game or for more precise values use the command /sensitivity 1 (Replace the number with your desired sensitivity).
Q: How can I change my Field of View (FOV)?
A: You can change your FOV by using the in-game menu or using the console command /cg_fov 90 (Replace the number with your desired FOV).
Q: How can I improve my FPS?
A: The best way is to go into the graphic options of the game and lower all the settings. The next step you can take is to lower your game’s resolution. Keep lowering it until you reach your desired FPS. If your FPS is still too low, there’s a good chance your PC isn’t good enough to play MW2.
Q: How can I report cheaters?
A: IW4x has no global control over server owners what rules they enforce / who they choose to ban. For this reason, if you encounter a cheater you must report them to the server owner you encountered the cheater on. Most servers provide contact information such as a Discord or website. Note: If a server has poor moderation and doesn’t ban cheaters, it’s advised you don’t play on their servers.
Q: Where can I download mods?
A: There is no one central location to download mods. For this reason, Google is your best bet at locating mods.
Q: What is the security level and why am I stuck on it?
A: Security level is a built-in security mechanism that generates a unique ID. It’s computationally intense and may take a while to complete. Please be patient.
