One of the three new Titanfall maps slated to arrive with the Expedition DLC ($9.99, or included in the $24.99 Season Pass) is called War Games. It plays up the virtual world/training simulator theme we've seen time and time again in gaming. I'm not totally tired of it, yet.
Respawn has detailed War Games in a new blog post that calls it "one of our most wallrunning friendly maps," which should be pleasing to hear. I'm not playing Titanfall right now -- not even after that close-but-not-tempting-enough $37 sale -- so I wouldn't know.
