Battlefield 2: Euro Force is a booster pack available from EA's download service. It doesn't have as much content as a full-blown expansion, but that's why it only costs ten dollars. What you'd be getting are four new maps, two tanks, one attack chopper, and a European jet. Players can take on the role of the elite Euro Force, who play almost identically to the core factions that already exist in Battlefield 2. The primary appeal of this booster come from the maps, which provide a nice variety of gameplay and justify the download even though they don't support 64 players.
