My friend and I got through all 12 waves but we didn't realize we needed to do it without dying. lol Anyway, I couldn't care less about the achievement, I just had a blast going through it so we're planning on doing it again tonight since it was really hard with just two people and then eventually 3. We thought we might be able to do it if we could have five players. Anyway, I won't be available until about 9pm MST, so if you're up to it, send me a FR. Thanks.
