10 years ago I was big in this game playing Team Fortress Classic. Its a server you play online with others. Red team vs Blue team and you play to capture the flag. Great strategy! Theres a variety of characters and each team needs just the right amount depending on your opponents team you may need to adjust yours and have somebody be a different class to help defend the fortress / capture the flag. Classes are: Scout - Heavy Demolition Man - Sniper - Soldier - Spy - Engineer - Pyro - Medic, etc. A lot of fun playing any of these characters and each have their own attributes. While playing Team Fortress Classic you can play just to have fun as a "noob" or get more involved with the game and play as if you were in the military! Have a headset so you can chat with your team members to talk strategy while defending the fortress. Communication is a must when it comes to military style games so if you knock down the opposing teams sentry guns (or snipers, or cleared their base of whatever whatever), its good to let your other team members know so they can advance forward (put more on offense than defense).
