Hello, little advice for this scenario, you have to leave 1 of the heroes behind, the one who will undergo the contamination. Another hero part ahead to discover the location of contaminated barrels. And the last takes care of the goons. Once the location is found, it must be that the hero to be contaminated is ready to perform his action. Whoever has gone to discover the location can eventually take care of dr. death. Finally after the contamination, you can go deep into the trunk to heal with the support of your teammate. It always ends on the last turn. And do not forget every energy cube is useful as well as its activation and rest management.
The marker for the container is on the board ; but you can't find it until another hero find where is the barrels.
The explosive gel is not necessary, but you can use it. After several games, you will be able to do without.
Enjoy the game
