Capture Flag
The title tells you everything that you need to know, but that doesn't mean Capture the Flag is going to be easy. This game has you playing with weapons against multiple enemies, so you're already disadvantaged. You need to be fast, but you also need to be cautious, which can be difficult when your target is obvious, and you can be seen from a distance. You must figure out the best ways to get in and out of enemy territory while still not letting any of them get into your territory. It will be a rough game, so you'd better arm yourself well.
