"Lair is a video game developed by Factor 5 and published by Sony Computer Entertainment America.
The player assumes the role of a dragon-riding knight named Rohn Partridge. Rohn is given the tasks of defending a certain area, destroying certain objects, eliminating enemies or creatures, and other mission-based objectives. After each stage, the player can earn either gold, silver, or bronze medals, depending on performance during the level. A platinum medal is also available, though unlike the other three its requirements are hidden. Earning medals assists in unlocking combos and behind-the-scenes videos.
Most of the game's battles are air-based combat, with some fought on the ground by landing the dragon and fighting troops and other land-based creatures. In some locations, the game features a morale system tied to the enemy; the lower an enemy's morale, the less he will fight, and it is possible that he will retreat from combat."
