When i got this as a gift 6 years ago for my Xbox, it quickly became one of my VERY favorite games.

This is one of the best games I've ever played. It is an incredible FPS that is a little underrated, but that's okay. Single player is pretty decent, has some fun moments. Difficulty is 50 50, meaning when they say hard difficulty, they MEAN hard difficulty! Multiplayer is great fun, especially on cooperative campaign mode. Arcade mode is just unbelievably fun. Yeah, you have Deathmatch, Team Deathmatch, all that stuff. But THEN, you get hilariously fun modes like Virus (One bot or player starts with the virus, indicated by a green flame raging around the character, and then the bot or player must find people that are not infected with the virus, and tag them. The man that is not infected wins!) Or you get "Monkey assistant" whereas the player or bot in last will get 5 monkeys with rocket launchers to aid them.

It does not end there. There is a system in the game called "Mapmaker" that lets you create your very own map for playing in these modes. It can be altered within the map, so you can make it a Story Mode map, create objectives with the trigger set, and also set bots, weapons, keys, crates, power-ups, and other items to help along the way.

Characters? Of course, there are HUNDREDS of characters to choose from. But the only drawback about them, is you have to unlock them, thus adding a challenge.

Speaking of challenge, if you're searching for a challenge, Timesplitters 2 has a challenge mode. these challenges range from throwing bricks through windows, to infiltrating the Siberian Dam (you must not be seen, you will fail the challenge. Plus, you are timed, making it harder.)

So, Timesplitters 2 is the next Halo. (I think Timesplitters 2 is better.)
