Ok I started on the speed runs and after the first I tried this one next because it had the worst ratio and I wanted to get it out of the way.
All in all it took about two hours from first try to getting it done, which is not bad for the first hard speed run to learn I think. So I thought I'd give you some more insights.
I used the RoosterTeeth video for my route and only did two small tweaks which I'll write about later.
First some general tips:
- He complains about the loading times a lot. If you install the game to your hard drive, you only have the elevator ride load times, and even those are faster.
- If you fail too much, don't restart. Instead, practice every section until you are sure you can do it without mistakes (like three times in a row). I even died on purpose at the end of each to train the sections one by one.
Some more insights into the sections:
First sections:
I didn't have any bigger problems with the first sections until you are in the elevator you'll have to leave through the roof. I usually got there at around 1:45.
Elevator shaft:
I slowed time (press X) to better coordinate the jump, also make sure you press LB when you're at the red line to hang onto it. After the drop, jump and the ladder, I did not practice the jump, wallrun, jump combo because I sucked at it and instead shimmied along the ledge and lost maybe 8 seconds, did not matter that much. The following orange section may take some practice but isn't that hard to master.
Blue rooftops:
I usually got there by 3:30, still enough time to go. Practice dodging the sniper's lines of sight and the final jump, shouldn't take too long.
At the end, where he is stuck in front of the elevator, press START, wait like 5 seconds and go on, the elevator will open then.
Server room:
You'll need about one minute for the rest, so if you arrive here by 4:55, it's still enough.
I wasn't good at aiming and wanted to kill both with the SMG, so that I didn't have to count on luck here after a perfect run.
So I practiced taking the SMG without slow-mo (press Y when he starts swinging), and activated slow-mo (X) right afterwards, so that aiming and gunning those gunners down wasn't much of a problem.
After training this section, the next time I got here with a minute time left, everything went perfect and I got the achievement.
Hope this guide helps you guys, this one isn't as hard as the ratio says if you're willing to put a little time into it.
I also love how the RoosterTeeth video shows that you can do a lot of mistakes and still have enough time left =)
