(Played before 2023)
One of the most revolutionary games out there. Having the story interwoven with the gameplay was really new, and the fact that it did it so well just really helps. The shooting feels great with a unique environment, and I loved running around the world fighting aliens and marines. It is so, so good. Everyone should play this game. I will say it is dated, and the source version of this game is completely broken, but this game is so fun. I only think the issue is the end game and Xen, which they admitted they didn't have enough time to work on this that they wanted.
