Doom – red, virus – green, chain with 2 locks – purple, shadow – white Doom bubbles at the bottom and a chain with 2 locks, there are also doom bubbles under that chain. There are two virus bubbles in the centre and one in each top, corner. Also a cluster of shadow bubbles above the virus in the middle
pic a – Make your way through the bubbles to the chain, try to get green spiders here to score points. Once you have unlocked the chain you will see the doom bubbles, work around these to clear the sides so they drop and the screen drops. Avoid as many shadow bubbles as possible and drop middle virus bubbles. clear the doom bubbles at the side.
pic b – Once the sides and middle virus are dropped you can see the ceiling. Clear you way around the doom bubbles on the ceiling and try to cut the virus off that is coming from the corners. Try to get green spiders before you drop that ceiling.
