Timesplitters 2 is absolutely fantastic. It is exciting, fast paced and very smooth. TS2 is great across the board.
In single-player you can collect game cartridges which you can play during the campaign mission. There are three to collect and they add great fun because you can play simple arcade games with mates, get high scores and it records it. You can really show off some old school skill. This is quite the fun little application inside the actual game.
Now onto the Arcade and Challenges, if you think the single player was a bit short or easy; now try these modes. In Arcade there are 2 choices; Arcade Custom which is the multiplayer, and Arcade League. Inside Arcade League there are 3 Leagues, each in progressive difficulty. These are fun and difficult. There are so many different missions which cover different game types and have a little bit of comedy to each individual story. It is downright fun. The other mode is called 'Challenges'. Challenges are similar to the Arcade League except for they are not necessarily standard combat. Some involve breaking glass in certain times or beheading zombies. This adds even more to the game.
Mind you, all these trials (single player story, Arcade and Challenges) help you earn more content in your game. This content includes more characters, maps, cheats and game types. Then you have the Arcade Custom Multiplayer. This is great fun. You can have more than 8 bots in one map, customise their skills, team and who they are. Also you can make yourself strong or weak, and allow special character abilities. There are 15 maps in total, each good for different game types. This game supports four players, which is really fun for beating your mates or teaming up. Whatever you want, Capture the Bag, Team Death Match, Gladiator, Virus, Assault, etc; there's plenty of fun to be had.
There is also a map maker which enables basic map editing features for making your own battlegrounds (it is quite impressive). Choose different tile sets and rooms. Make hallways, bottlenecks and strategic defensive points. Now, your single player and multiplayer exploits are recorded for viewing later. Kills, Losses, Accuracy, Time Played, etc; there is a lot. This game is just fantastic and has a great soundtrack as well. The game is just fantastic and has a long life.
