Fan Project Combines Half-Life 2 With Games Like Max Payne and Hotline Miami
Although Half-Life is considered one of the most influential FPS games of all time, Half-Life 2 was able to build on what made its predecessor so well received, showing that its developer had the chops to do a magnificent sequel. In fact, Valve had a lot of success early on, and while it's mainly known for its Steam platform these days, there was a time when it was a near unstoppable force in game development. Alongside this, there are still people in the community making mods for the 2004 sequel, and some projects combine the efforts of many people.
