Moonlight Online is expected to launch at the end of the year, and we're slowly getting more information on the game. The latest information from IGG gives a few hints about what we can expect from combat.
While it's light on specifics, we do know that Moonlight Online "utilizes DOTA-like tactical elements in combat, so gamers can have their characters cast spells and use abilities in while in motion (limited by a cooldown time)." Transformation will be a big part of Moonlight Online, with characters gaining some impressive stat boosts in their alternate forms. Werewolves will receive buffs to attack power and HP, and vampires in bat form will be faster, more agile, and have a spell power boost.
You can find more details about IGG's take on the vampire vs. werewolf conflict on the Moonlight Online forums.
