The Io Games category on our website is without a doubt one of the most beloved categories of multiplayer games we have here, and we know for a fact that our visitors want us to bring them more and more such games here as often as possible, which is why right now we are returning to it, and offering you all the game called Madness Io, which we are positive you are going to greatly enjoy from beginning to end, since it is one of the best shooting games this category has had recently. We explain how it works right here and now, so you should not have any difficulties in playing it at all! Start by choosing the name you want to use in the game. With the W, A, S, D keys you are going to move, and with the mouse, you aim and shoot your gun. It is going to be just like in battle royale games, so what you have to do is shoot everyone else before they get the chance to shoot you because they are going to try that since the last one standing gets to climb the top of the leaderboard. In the end, we can only wish you all good luck, and invite you all to check out all the awesome games we will be bringing here today for free!
