What is this strange robot called!?
A few days ago i was playing the E3 2002 until i found this weird robot that makes a screeching noise, here is the screenshot i took https://drive.google.com/file/d/1MNDL33i-KJlHZHogEIU1AmmKGiE25f_I/view?usp=sharing

I hope someone tells me the name of this weird robot, because i am very curious about this strange orange robot. 

And also this robot is from the e3 2002 map "e3_terminal"
