We're not discussing gameplay in general, we're discussing speed (both walkspeed and the time it takes to ADS).

I tried testing it, and it was pretty inconsistent.

Too bad speedrun.com doesn't let us submit runs for other players.

The class to use depends on the mission too.

There's a list of WR seeds on the Wiki's page on Speedrun Mode: https://entry-point.fandom.com/wiki/Speedrun_Mode

For The Financier, the seeds are the following: 3 - Rookie Solo

87736 - Rookie Duo

884689 - Rookie Trio

724978 - Operative

675500 - Legend

It works because you put the keycard in.

Intimidation perks.

When you submit a run, it specifically says "ms" which is short for "milliseconds." The game uses centiseconds, but speedrun.com uses milliseconds, so submitters will have to manually convert their times using the process in this guide: https://www.speedrun.com/rblx_entrypoint/guide/4kpep

All of these seeds have the power box at the right, but unfortunate they also have a camera facing it; I could not find a seed that has the power box but doesn't have the camera 913086 or 269665 - Maddox Grey's office is next to the top camera room 805076 - ID in manager's office

In The Financier, you can speedrun getting on top of Ryan's penthouse.

In The Deposit or The Cache, you can speedrun getting on top of that thing that Carrot used to get the thermite stuck in that one video.

For BD, loud takes a bit over 10 minutes while stealth takes a bit over 12 minutes.

I'm thinking first 5 stealth, Scientist and SCRS loud, then either tactic for BD. Does anyone have a better strategy?

As of now, Bawak has the unofficial WR of 1:19:24 with an Infiltrator. Is that really the best class for Ironman Legend Solo speedrunning? If not, then which class is?

The best class for speedrunning Withdrawal is Technician so you don't need to waste time getting the blue keycard.
