As successful as online MMOs have been (we covered 16 of the best here), it would be churlish not to mention the genre's equally popular cousin, the shooter. A genre that has been synonymous with video games since the dawn of time – well, since Space Invaders at any rate – the shooter has gone through many incarnations with the latest and greatest evolving into the online free-to-play market.
With that said, we thought we would take a look at the best the medium has to offer. So here are 15 awesome f2p shooters.
Note: If you're wondering why we didn't include Planetside 2, it's because we represented it in our best MMOs story.
Do you have a favorite free-to-play shooter that you would like to share? Let us know in the comments!
