I've been thinking about this lately. The final objective in the Halo Reach Campaign is listed simply as "survive". Is it possible to do so on Legendary and is this the "clue" we've overlooked to possibly unlock an alternate/Legendary ending? What I mean is not simply surviving for a set amount of time but to actually kill every enemy and thus survive the mission? From what I've read in previous threads it's supposed to be impossible. The enemies continue to spawn until Noble 6 is killed. Some have claimed to have gone as long as thirty-minutes killing enemies only to have new ones appear. This may or may not be true, the longest videos on Youtube I could find were about seven minutes or so in length for players attempting to survive on Legendary. There are several videos of groups of players playing at lower difficulties and surviving up to ten or so minutes. But is it possible that the Lone Wolf mission is set up much like a firefight one, with increasingly difficult sets of enemies but an eventual end to them? It's notable that the elites who spawn are increasingly higher in class and better equiped, much like in firefight mode. It seems impossible, Noble 6 is at a marked disadvantage especially given the helmet cracks from taking damage which knock out a player's HUD and will trigger the ending if additional damage is taken even if Noble 6 still has minimal health left. On the plus side there are a great many starting weapons and a defendable postion for Noble 6 to occupy as well as a few health packs that can buy a player alittle time. I have to wonder if a highly skilled four person team (much like the max team no in firefight) would be capable of surviving through the "waves" if you will of enemies? Perhaps this is the ultimate challenge and test of skill and teamwork that has been elluded to as leading to "something special"? What are the community's thoughts? Is this a possibility at least? Just thinking out loud I guess, sorry for the long read.
