it's quite easy to pass the level, more so in Multiplayer. In single player, just ignore all loot, only kill necessary zombies, grab the vaccine ASAP so it doesn't change location, and ignore the boss. If you have a good gun (I.E. Striker/Planet Stormer) you can aim for the loot, but unless you are really experienced, ignore the boss (I did take him down though, i got a really good striker from an iridium box).

In Multiplayer, it's really easier, but rather cruel XD. It doesn't matter if you have 2 or 4 people in the team, tell them you will be defending their backs and they can rush in front. Normally they will encounter the MOST zombies, so when you grab the vaccine use them to distract and attract all Zombies in the area, and make a quick dash for the evac plane. From there, shoot out the plane to gain kills and experience. You will be able to survive rather easily, with extra XP for being the survivor, and have a decent kill count.

In the case where you notice your team has a really strong member (I.E. I got into a level 3 rookie level with my level 13 assault XD) do NOT dash for the plane. The experienced player should and will take down the boss as well as most of the zombies, so you can just hang back, offer support and grab the loot :)

Hope my advice is useful
