Valiant is a unique, side-scrolling 3D MMORPG game developed and published by international gaming portal, NTTGame. Valiant ignores the typical restrictions set by a side-scrolling MMORPG, and includes various unique combat mechanics, an in-depth dungeon system, and a large variety of other features that you would usually only associate with a premium MMORPG game.

Valiant uses the highly versatile movement system, featuring the arrow keys as movement and Z, X, C, V as abilities and combinations. This creates for a much faster combat system than typical MMORPG titles that focus on macro and hot-key abilities. Valiant also adds 2 other mechanics to the combat system, Skill Change and Final Attack, both of which are a first for a side-scrolling MMO game. Valiant does not restrict skills and abilities to certain classes, instead they're attached to weapons. There are a large variety of weapon types available, all of which offer players different abilities. Players can switch between weapons freely during combat, and can even assign a key to the task, allowing them to switch weapons, perform an ability and switch back, with just 2 key presses. This creates a unique combat system that allows players to effortlessly link skills and abilities. The other unique combat feature, the Final Attack system, is reserved for tough boss battles. Once a boss reaches low HP players can activate the Final Attack to launch a quick key-pressing based mini-game, and if successful, it results in a devastating ability to finish off the monster.

Another great aspect to Valiant is the unique dungeon system, featuring exotically themed dungeons all posing different challenges. Dungeons are filled with mutated monsters, difficult boss fights and a huge variety of traps to test a players ability. During dungeon raids players can also mount the enemies they fight, reducing their HP and jumping aboard to ride around the dungeon slashing apart their enemies as they go.
