This is a round timer I made for my Killing Floor Maps I am working on. Every time the circuit is activated, it flips the next latch in line. To reset the latches, you activate the reset line in the back of the circuit (shown in the picture). If you wanted, you could create an infinite round as well by linking the final latch to the reset switch.

Feel free to use this in any adventure map and/or game you want, just make sure to give me credit!
