This one's my own current personal favourite to play.
I notice very few other players manage to grab the shield though so here's a tip on that. It's really not all that hard, but it's not just a jump, you have to jump, turn into the wall and then wall-dodge to the shield. The jump/wall-dodge can be started with a lift-jump or a regular jump off the platform at the top of the lift.
A little trickier but it's also possible to get to the shield with a wall slide.
Seems like this one has become a favourite on the server. Ripper is insanely good in the narrow tunnels, I thought there might be complaints about that but everyone I've seen say anything about it so far is loving it (the Ripper that is).
