Very good DLC, well worth the price.Qwertyfour | Sept. 27, 2013 | See all Qwertyfour's reviews »
This DLC packs add two fantastic co op/single player missions which are absolutely fantastic, in addition to a couple of pretty nice equips. The crossbow weapon is a direct nod of approval to the developers of Dishonored, who featured a protagonist who would often use a crossbow that shot sleeping darts.
In playing through the mission, the crossbow proved to be quite useful when going for no kills. The boat mission is pretty inspired but I'd think that playing in co op would make the boat a bit too condensed in that it feels a lot more like a single player mission. From my experience, me and my friend ended up running over each other and ended up gunning everyone down but perhaps my friendship is not on a "play co op games" level, haha.
Overall, buy this DLC if you enjoyed the single player missions.
