Okay, here’s some co-op routes by me and Inexistence:
Note the button glitch; if player 2 jumps on and off a button quickly, sometimes the game will act as though the button is still pressed.
Note the gesture skip.
mp_coop_laser_2 (first room):
Nothing too clever here, but this portal placement is faster than the more obvious ones.
Two big things to note. Thing one is that you can grab a cube through the delivery tube at the seams (is this possible on any other levels?). Thing two is that one player on their own can hit both levers to open the door that is meant to require both of you.
A theoretical route here. We reckon it should be possible to get the cube to land on the button.
Just airstrafing to avoid landing on AFPs when the game intends you to.
At the start, you just need to deliver two button presses in quick succession to open the door. They don’t actually have to be on different buttons.
After that you see the reportal trick being used to reach the AFP.
A couple of tricks here. Firstly, you can drop from an ExFu onto the railing and from there strafejump onto the portalable surface in the centre of the water to gain faster access to the room with the button. Secondly, we pull off a neat ball throw through a portal and catch it with the ExFu to get it to the laser faster.
