RESIDENT EVIL RESISTANCE

Get up to 10 Bio Energy and place yourself next to a door and a light switch. Use the lowest value cards you have (save your refresh card if you have it for when you only have 3+ value cards) and lock a door/turn off the lights when your Energy is low to regain some quick. Swap cameras to another location you can shut off lights or lock doors if you need to. If you use nothing but 1 and 2 value cards, this should come long before a minute passes.
