XDefiant is a fast-paced first-person shooter for fans of most of the Tom Clancy franchises Ubisoft has released a game for. It includes factions from The Division, Ghost Recon Breakpoint, and even Splinter Cell. However, it comes with all the issues that most online shooters face, including bugs and errors that can plague a community for days on end. One of the biggest is the Mike-01 error, which happens to have a relatively simple fix for those who need it.

To fix the Mike-01 error in XDefiant, you need to make sure you have the correct version of the game downloaded. At the time of writing, the XDefiant Server Test Session is well underway for the weekend. However, you can’t play it and will get the Mike-01 error if you haven’t downloaded the Server Test Session version of the game.

To find the Server Test Version of XDefiant, launch the marketplace on the platform you want to play on. Then, search for and open XDefiant before selecting the Server Test Version from the available options. The Mike-01 error is impacting PlayStation users the most, so use the ellipses button to select the right version.

What is the Mike-01 error in XDefiant?

The Mike-01 error in XDefiant is known to be caused by trying to play the wrong version of the game. There have been many betas and playtests for this title, and while all will connect to the game’s servers successfully, only some are active at any given time.

At the time of writing, the Server Test Session is welcoming as many players as possible to see how far the game’s serves can be pushed. However, if you try to launch the full version of the game or another test version, the Mike-01 error pops up and prevents you from getting into matches.

The Mike-01 error is so prevalent in XDefiant that Ubisoft posted a message on the game’s Twitter account. It did this to show as many players as possible that there’s an easy fix, but also because it was getting so many reports of the error.

To avoid issues like this, I always try to delete the old versions of games I play Betas and Alphas for, just in case errors similar to this can occur. It results in more download time but avoids unnecessary faff when all I want to do is get into a game.
