I haven't been paying too much attention to the goings-on of X-Force or Cable lately, I'm a poor college student and don't find the art for Cable that appealing. But I was told this story was going to be on-par with Messiah CompleX and treated as a second act, so I picked it up.
I know the basic idea behind Cable, he's protecting the first mutant, Hope, born since M-Day and doing a lot of time traveling to do it, so catching up with all that wasn't too hard. And while there is some set-up through Cyclops' narrative to bring a fresh reader up to speed.
The real story really starts cooking as Bishop, the man chasing Cable through time, is talking in a bar to yet-unknown figure. Without spoiling anything, the identity is very important to the series (of course) and pays off at the cliffhanger. After Beast finds Cable in the timeline, X-Force is teleported through time to roughly 1000 years in the future and run into my buddy Deadpool.
There is a scene in the last third of the issue that may stand out as the best Deadpool/Wolverine material in a very long time.
Cable shows up at the end, there is a cryptic feeling behind his actions and a reveal of a large futurist city that Wolverine seems to have seen before.
If you've enjoyed Cable or X-Force, you've picked this up already. If you like Messiah CompleX, I think this might pay off. The X-Office at Marvel hasn't been letting me down much lately. Other then the fate of Madrox's kid... that was a little bad. But funny.
