Now some of you may being saying "omgwtfbbq, how can you play by yourself, die, and still win a campaign?!? H4X"
Others of you may be saying, "Ha, TOO BAD I KNOW HOW THIS WORKS."
So, without further ado, I will, on TWHL, reveal some not-at-all-rare information involving Left 4 Dead 2 (yeah this is 2, despite it saying Bill, right?).
Anyway, what I did was I simply played The Sacrifice campaign with the Last Man On Earth mutation. Nothing special.
THIS is where questions may be asked. "But LMOE was long over by the time The Sacrifice came out!"
True, but with a simple console command, you can play any campaign you'd like on any mutation you'd like. You can even host a dedicated server to do this, but it'll essentially be friends-only.
Command is simple:
'map [mapname] mutation[#]'
For example, to do the sacrifice on LMOE you'd type:
'map c7m1_docks mutation1'
Tada. Now I suppose you'll want a list containing all the current possible mutations:
mutation1 Last Man On Earth
mutation2 Headshot!
mutation3 Bleed Out
mutation4 Hard Eight
mutation5 Four Swordsmen
mutation6 Nothing
mutation7 Chainsaw Massacre
mutation8 Ironman
mutation9 Last Gnome On Earth
mutation10 Room For One
mutation11 Healthpackalypse!
mutation12 Realism Versus
mutation13 Follow the Liter
mutation14 Gib Fest
mutation15 Versus Survival
mutation19 Taaannnkk!
Just finished No Mercy on Expert in singelplayer with Gib Fest mutation. Loads of fun!
Few good achievements can be earned as well.
It's speculated the first Tank in The Sacrifice (the one in the train) is weaker than a normal tank. Play on easy, Last Man On Earth, chainsaw, VRRRRMMMMM. I got Tank Burger this way.
Also would make doing Level a Charge, Sob Story (I actually got that one on a normal game w/ 3 bots), and some of the other ones a lot easier.
But you'd have to make sure it gets its own thread/news post.
