Hehe, I knew this thread was a good idea.

Gordon comes with the base of the alleyway, and Selina comes with the catwalk, so you just need those two. (Although later this year Bullock is being released with another piece that has a dumpster). The figures will run you about $25 if I am correct.

Now, important note! Toys R Us sells versions of these figures that DON'T come with the display bases. So if you want the bases, you'll have to shop elsewhere.
