World of Van Helsing: Deathtrap

Play any map you want (darkmoore is probably the easiest) and select "Scenario mode". Now, add atleast 10 stars (difficulty levels) to the different stages. You can pick whatever you feel like but some are more difficult than others. I'd recommend to stick to the easier ones like gaining less gold / xp / rage.

Once you've finished the map your achievement will pop.
