Steel Battalion: Line of Contact (鉄騎大戦, Tekki Taisen) is a 2004 video game created by Capcom for the Xbox console where the player controls a VT (Vertical Tank). It is the online-only (via the Xbox Live broadband gaming service) sequel to Capcom's Steel Battalion game. Gameplay is similar to that of the previous game, and makes use of the same 2 joystick, 3 pedal, 40 button controller.
Gameplay is entirely online and consists of various game types (such as deathmatch, capture the flag, and others). Up to 10 players (five against five) can supposedly participate, and each player must have an Xbox, Xbox Live, and the special controller to play the game. However, at this time everywhere except Japan, most matches are limited to 3 vs. 3 with the some 4 vs. 4 and rare 5 vs. 5 combat. Players connecting with less than 100 kB/s up and 300 kB/s down are usually limited to 4 on 4 or 3 on 3 combat. There are a total of 10 new VT's introduced in this game, for a total of 31 different models, but it is worth mention that there is no single player mode available. After having their VT destroyed during an online match, the player must go through the entire start-up process again before re-spawning onto the battlefield.
