Move to the left corner of this platform, shoot the target again to flip it from green to red, and quickly jump onto the next platform to the SW as it rises and the one you were standing on collapses.

There's another red skull (9/10) on the next folding platform to the north, which is collapsed.

Shoot the target again to flip it from red to green. Quickly jump onto the platform with the skull as it rises and the one where you were just standing collapses.

NOTE: Alternatively, you could make your way across from the target to the red skull via the platforms to the NE, as shown in the single-player walkthrough.

Move to the bottom edge of the platform where you found the skull. Shoot the target once more to flip it from green to red. Then quickly jump back onto the platform to the SE as the previous platform collapses.

From here, you can jump over to the large, square platform with the urns. Smash them to get 3 ammo and several gems. As long as you don't step on the NW edge of the platform (outlined in the screenshot above) you can move about freely without triggering the next set of enemies.

Shoot the target way off to the NE again. Jump across the 2 platforms to the SE to find a HEALTH UPGRADE. Then return to the large, square platform where you smashed the urns.

Move over to the NW edge of the platform to trigger the appearance of 2 shield demons, along with a few minor enemies. You can fight them here if you like or jump back onto the previous folding platform, as indicated by the arrow in the screenshot above.

The enemies will not follow, and you can shoot them from safety.

Alternatively, when the shield demons appear, jump down into the room on the left to fight them. You'll have more room to maneuver, but you'll also trigger a few additional enemies here. This is actually the area where you first encountered the shield demons earlier. Any supplies you didn't take then should still be there. (This screenshot and the one above show the single-player game, but the area is the same in co-op.)
