Dungeons 2

(Offline or Online)

The Rolling Stone is a trap you can research as the Horde either in campaign or skirmish or online mode. The research option for this trap can be found on the Create-O-Mat in Tinkerer's Cave rooms, in a Level 2 Dungeon. Once researched and deployed then triggered by approaching enemies, the trophy will pop. It's highly unlikely you will miss this trophy as the Rolling Stone trap is one of the cooler and better traps to deploy in your dungeon. To upgrade your dungeon to Level 2, you need to accumulate Evil, by attacking and conquering Overworld sectors by destroying spawn camps and changing the landscape from Good (green) to Evil (red) or easier still just start a skirmish or online game and set the starting dungeon to level 2.
