Special Force (named Soldier Front in North America) is an online free-to-play first-person shooter game developed by the South Korean video game developer Dragonfly, which is based in Seoul. Although a small company, it is notable for releasing many popular games both inside and outside Korea, including: Special Force and Karma.

Special Force provides several game modes including team battle (bomb planting, escaping, object stealing, etc.), single battle, team deathmatch, and horror mode. Most modes consist of a red team and a blue team, with the exceptions of a single battle, training, and horror mode. The game allows for a maximum of 16 users to be in the same room playing together.

Players can purchase and utilize a range of character forces, including French GIGN, German GSG 9, Malaysian PASKAL, Republic of Korea Marine Corps, US Army Delta Force, and Russian Spetsnaz. Players may also rent equipment for speed and armor. Various modern-themed weapons are available. Weapons have durability and must be repaired often. They cannot be modified like in other first-person shooters, but once they are purchased, they are permanent and stay in the inventory until the player sells them.

Players rank up after receiving enough experience points, gained after each match, with bonus rewards at certain ranks.
