Clear as crystal... This map has a secret ending where if one person collects all the crystals (theres 6 crystals in total) and has them all at the end of the map, you get to see the secret ending. It sounds easy, but it is not because if you get 4 crystals and die you have to go get them all again whilst your team mates use a shortcut and maybe do the next bit. Fortunatly for you, me and Illusion collected all the crystals and I have recorded the secret ending (watch the videos here: Part 1 - Part 2). I am now going to tell you where to find each of the crystals so you can collect all the crystals for yourself.

The red crystal: The red crystal is at the beginning of the map after you have been waiting in the hotel, viewed the van crash (my favourite part) and watch ufos attack the planet... The red crystal is underneath the yellow/white blue striped block and next to the fire.

The orange crystal: The orange crystal is in the water, past the slightly open door and in the corner.

Thats illusion with the red crystal on the first picture, forget about where that is on this picture!

The yellow crystal: The yellow crystal is up the red ladder and to the left of the health pack on the wall.

The blue crystal: The blue crystal nearly everyone knows where because it is very obvious but incase you do not know it in in the middle of the fan room at the bottom. Acid surrounds it and can be hard to get so this is how you get it:

1) Get passed the two fans that try to blow you off the wire (jump to the wires makes it easier).

2) Wait for a team mate to get passed the fans aswell.

3) Go up the ladder to on top of another fan and press the button.

4) Go back down the ladder then walk down the first wire you come to, then jump off it onto the bit in the middle with the crystal.

5) Jump near the middle back onto the wire you just jumped off of.

The indigo crystal: The pink crystal in my opinion is the most dangerous crystal to get to. Just before the pink crystal there is 4 steam towers that you must jump over with the help of your friends. I can not really help you on how you make the jumps but try get your friend(s) to press the steam tower your about to land on so you take no damage. Once past the steam towers you will probably run past the crystal without realising. This crystal is however difficult to see and get compared to the rest (exception to blue). It is underneath the grated platform and you must get on the side rail, crouch and slowly back off then when you fall push forward (still crouched) to get on the rail underneath.

The violet crystal: The purple crystal is in between the middle of the spinning platforms (underneath the grated bridge) in the power generating room. It is fairly easy to get once there switched off. Just drop down onto it then fall off.

There you now have all 6 crystals, have fun with your new ending.
