I haven’t played much the last 10-15 years, so I’m extremely rusty. Am currently playing Campain alone (i.e., not online) and is on my second round of Reach.
But is the last map, Lone Wolf, possible to finish? The enemies just keep coming and I’m not allowed to leave the ‘slaughter zone’. The mission is ‘to survive’ so it indicates a possibility, but so far I’ve struck out badly!
