Lost Saga

Lost Saga is a casual free-to-play 3D fighting game. Developed by I.O. Entertainment in Korea, Lost Saga officially launched its North American service on November 17, 2009 by OGPlanet and its Indonesian service by Gemscool.
However, as of February 18, OGPlanet has shut down their service for the North America and European Servers of Lost Saga. The company that will bring it back to life is WeMade USA (a subdivision of WeMade Entertainment), a company that is in close partnership with I.O. Entertainment. WeMade USA planned account transfers, but due to the lack of account data/information, transfers were not possible. The games release was intended to be on February 26th, however, on their Facebook page, the company stated that they would have to postpone the release to April 11, and apologized for this. WeMade USA plans to officially launch Lost Saga out of Open-Beta on May 2nd, 2013.

Mercenary

Characters in Korean Lost Saga are entitled "Mercenaries" or "Heroes" in KR, NA, EU, ID and TH versions. Mercenaries are divided into five different categories: Melee, Ranged, Magic, Special, and Premium. Players can purchase mercenaries from the in-game shop using pesos, the currency earned from battles, or earn their services for 2 hours when they reach the rank at which that mercenary is unlocked, with the exception of premium mercenaries, which can only be obtained through gold (KLS's cash currency), Astros (NALS's cash currency), Gcash (IDLS's cash currency) or through mercenary scrolls, which can be purchased for 3,000 pesos in the shop. (KR, NA, ID). Players may obtain as many mercenaries as their inventory slots allow. By default players are allowed 12 Mercenary Slots and more can be added by purchasing the slot item from the shop.
Once players place their mercenaries in the inventory they can switch between them by pressing number keys (this can be changed in the options menu). This method allows the players to freely change into different mercenaries during gameplay, but only if the mercenary that is currently in use has 4 gears equipped (this is not to be confused with style items e.g. hair).
In addition, "epic gears" are mercenary equipment with an alternative design. They enhance the game by allowing players to equip different gears to the mercenaries they've hired. However, epic weapons can only be equipped to their corresponding mercenary. Epic gears provide not only a change of costume, but a stat boost that varies with each gear. The gear's skill, however, does not change. Premium mercenaries do have epic gears, but they don't look different from the original ones (With the exception of Sol's epic weapon). There are also special gears titled "legendary gears". Unlike epic gears, these gears do not correspond to any existing mercenary. As such, most legendary gears have no alternate design and there are no legendary weapons. Legendary gears may also use multiple skills in one gear e.g. jumpers and some come in multiple designs e.g. bunny ears (pink and black).
