EA has its Battlefield games, and Activision recently shipped Enemy Territory: Quake Wars. Now THQ is looking to get into the large-scale multiplayer action genre with Frontlines: Fuel of War. What distinguishes these games from regular first-person shooters is the scale; while a typical shooter features infantry combat only on smallish maps, a game like Frontlines will allow up to 64 players to fight it out on large levels using a mix of infantry and vehicle combat. (The console versions of Frontline will support up to 32 in a game.) Frontlines will be the latest of these games, and its designers know something about the genre, as they previously worked on Battlefield 2 and the popular Battlefield 1942 mod Desert Combat.
