Improved on my high score even further today, which is just as well as a couple of people on my friends list were inching closer. I’m now at just over 13,000, which should hold off my nearest competitor (SomethingWitty) at 10,000-ish for a while. Had a few more goes online in Coop mode, and the lag was awful again so gave up. Did manage to unlock the Chicken 2 achievement, though, as well as another one for completing Level 4.
