Time and time again, Steam comes through for its loyal fanbase in the form of free games. It happens every month it seems. The month of May is no different. As of this weekend, Steam users will have the chance to play the iconic Left 4 Dead 2 free of charge. \n \nYou don't want to miss out on this free-play weekend, especially considering just how fun Left 4 Dead 2 is to play. This cooperative first-person shooter has a lot going for it. Published by Valve Corporation, this sequel originally debuted all the way back in 2009. \n \nTen years have passed and even still, this game is amazing to play with others. It uses the same Source engine that was used in the original. There are four new survivors to choose from, including Coach, Nick, Rochelle, and Ellis. They all have unique personalities, making them easy to get attached to. \n \nhttps:\/\/youtu.be\/9XIle_kLHKU \n \nThere are many modes you can explore as well, including campaign, versus, single-player, survival, and scavenge. As far as the infected in this game, they are pretty brutal. There are new additions that pose all sorts of challenges, especially later on in the story. The Witch is particularly startling to come across. She can kill a survivor with just one blow, making it all the more important to use stealth tactics when around her. \n \nThere are a total of five campaigns with several levels included in each. As you progress through each level, the AI gets progressively harder. You're thus forced to adapt after several sessions, which keeps you on your toes. \n \nThe weapons in this game are a blast to use. There's something for every situation, including shotguns, grenade launchers, and melee weapons. They're classified into different tiers. The higher the tier, the more damage that weapon can do. \n \nWhat's most important about Left 4 Dead 2, much like the original, is its focus on cooperative play. You can enjoy the game solo, but you'll have a much better time in sessions with some friends. You truly feel like you're surviving together in the zombie apocalypse. Strategy and teamwork are necessary to pass each stage. \n \nEven if you've never played a Left 4 Dead game before, this sequel is incredible to experience. The zombie variety is incredible and you would be hard-pressed to find a better zombie game to play with others. Thanks to Steam's offer, you can experience all of this epic zombie action without paying a dime.
