So I'm loving the machinima bits- they are far superior to the ones from Season 9 and, for whatever reason, I'm happy they're using Halo 3 again. Reach was just a little too different to be used, I think.
The CGI section was brilliant as always, and continues to blow me away at how far they've progressed in terms of visual quality since Season 9. Also, it was nice to see another big ship.
Now to wait for Episode 5 tomorrow!
Also... Meet the Pyro.
