Marvel Rivals Season 4 offers numerous cosmetics that can be obtained for free. While its Battle Pass is great, purchasing it is not necessary to get new skins. NetEase offers eight free skins at the moment, and one of them is a limited-time costume for Iron Man.
This guide will explain all the steps you need to take to unlock the free skin in Marvel Rivals. The entire process is straightforward, and you can add the skin to your account in less than a minute. The best part? The skin has unlimited quantities, so that you can share it with your friends!

How to unlock free Marvel Rivals skin for Iron Man?
The free Iron Man skin is called Armor Model 42 and was previously available for a few months. NetEase offered it to players with a code, which expired in March 2025. However, the skin has now returned, and you can redeem it for free with a new code.
To get the free skin, you need to launch Marvel Rivals, open the main menu, and choose Bundle Code. Once a new window opens, type SNMRIronman in it and confirm. As soon as you do this, you will receive Tony Stark’s costume.

The skin can be redeemed on any platform, including PlayStation 4. However, it will expire on December 18, 2025, at 11:59 PM UTC. This gives you more than enough time to obtain it, as the entire process lasts for only a minute. This also means that the skin will be available on the release date of Marvel Rivals Season 4.5, so you don’t have to rush it.
