The super scripted boss looks nice, a (somewhat) highly mobile mech suit. But it can be "killed" easily if you manage to hijack it. Not sure if that's the intended way to defeat it.
There's probably a bug in the second map. I failed the map for letting the mech suit at the end escape. When I restarted the map, I suddenly won within 10 seconds for no apparent reason. Guess the mech suit got respawned and fallen out of the map or something.
