A Should-Add
*Note: This review is, word for word, taken from a longer review about the original game, Dungeon Siege 3. Please note, however, that I wrote that same DS3 review myself and therefore is not a case of plagiarism.
Treasure of the Sun, a DLC for Dungeon Siege 3, is an outstanding addition for the game, thanks to its storyline and additions to the gameplay that make it a bit deeper.
The DLC starts when you accept a quest from a former Legion servant who wants to find his master in the Desert. You travel there and find an abbey full of rogue churchgoers, who didn't follow Jeyne even when she had the church wrapped around her little finger. From there, the player tries to open the vault, where the master is, and later search it to find him. The plot sounds simple, but the context is incredible. You'll know why the churchgoers left Jeyne's side, the reason for the master's entrance to the vault, and why the leader of the abbey is kind to Legionnaires despite the political climate. There's just a lot going on, and the game really tells you what is exactly happening. The story blends in nicely to the overall plot and is enjoyable, a plus to the DLC's developers.
But more importantly, TOS has a couple of extra features to the game. There are 3 more super cool abilities for the player to use. A massive healing ability, an invinsible barrier or an offensive wave that damages incoming foes. You can only use one ability at a time, and they are all cool add-ins. But the real additions are the essences, which you can add on to weapons and armor to implement an effect like Warding (stunning opponents). This adds more customization to the characters, bolstering the game's RPG part. The game also addresses the loot issue with some really powerful items that are both unique and powerful, so finally the player can have some variety with its equipment. More importantly, the equipment makes the rest of the game a lot easier, thanks to the huge stat boosts and alot of leveling up.
But with such new additions comes great dangers. TOS has got to be the most difficult part of the game. Once again, the enemies are extremely fearless and will attack you at every turn en masse. I remember dying only once or twice in the game before TOS. With it, I lost more than 5 times, a complement to the game's difficulty level that is harder but not cheaper.
TOS also has its share of side quests, all of which are close to the main objectives anyway. With it you can tack on 4-5 more hours for the game, a necessity given the briefness of the main campaign.
At the end of the day, TOS is a great addition that improves an already strong narrative and bolsters the game's RPG component. If you like the game, especially the combat, this is a must get.
