[quote name='Jon7']Very short, and basically consists of running from one point on the island to another to fight groups of enemies. Only recommend it if you really like old kung fu movies and want to play a parody of one in Sleeping Dogs. It's not terrible for only a dollar though.[/QUOTE]
[quote name='Solid-Snake-Eyes']I played a chunk of Nightmare and I liked it. I look at the Sleeping Dogs DLC like this: I loved the game, I want more of it, for $5 or now $1.25 if I can get a couple more hours of Sleeping Dogs then I'm interested. It doesn't have to blow me away, but you don't always get single player DLC episodes for games like this and I'm glad to get a bit more game without having to wait 3 years for the sequel.[/QUOTE]
I agree with both of these. I loved SD and Nightmare in Northpoint was probably the only DLC I bought near release (with a GMG coupon I think).
Don't look it at as continuing the game, but more of a halloween themed side story. It's fun in that sense and a bit campy.
