So you're muching on that RT, helping the team out. A marine comes near on the other side of the hallway, but you don't worry, you're protected by being behind the resnode. Thats what you thought until he pistolwhips you from across the hall.
There is a safe way to bite the res node:
Step 1: Pick the best angle. The best angle is the angle that is 180 degrees from where the marine is most likely to come from.
Step 2: Get in the body of the res node. That is, the main big fat part, near the top. You'll know you're in it because you can then see right through the res node. Make sure you're in the correct position then start biting now.
Step 3: While you're biting, this is the important part, Move to the left or right EXTREMELY slightly ONCE.
What does this do?
->When you position yourself at a 180 degree angle from the marine, the res node's hitbox blocks the marine's fire. This forces the marine to come VERY close in order to register any hits on you, in which case it is to your advantage.
->Even though you can crawl into it, the body of the resnode does have a hitbox, and will block bullets. Once in it, you can also see through it, giving you a visual advantage as well.
->Once in position in the body of the res node, moving slighty to the left or right causes you to turn SIDEWAYS. This allows your body to be completely covered by the res node, yet makes no difference to what you see.
You'll find yourself a bit slow getting into position at first, but once you practice, you'll be able to take down res nodes without fear of being pistoled from miles away.
I'll get some screenshots of it later.
