Need the 5 achievements for The Sacrifice campaign so I can reclaim my 100%.
Having to buy it twice, once for each game, is total BS. Friends didn't have 100% ach on part 1 prior to the Sacrifice DLC, so they don't want to re-buy it for L4D1 (can't say I blame them).
Anyone that has The Sacrifice for Part 1 that wants to play, please hit me up. Will help with any other ach's in return! Thanks!
