Temple of the Raven Hidden Room
This is an example of one of the glitches in Uber Strike that you can exploit to your advantage.
On the Temple of the Raven map, head to the third floor. You should see a bird, which you need to shoot, at which point it's eyes will light up. You need to be quick now and sprint to the ground floor before shooting the two hanging birds.
Once their eyes also light up, you should appear underwater. Turn around and notice the black box - go inside and you will transport to the secret room!
