well you could try using the game search to find shooting games. The games are (probably) not gone, but just not directly accessible temporarily. I am sure they will fix this soon, but its obvious they were working on the site today between all the major glitches I saw in the forums, along with this.
Yes, there have been many glitches and the site has been running slow. But this is all due to site maintenance. The site should be running smoothly in a day or so.
