did this the other day took 2hr 43min and I thought i got thru fairly quickly....DAM 6.32sec.....VERY IMPRESSIVE.....never thought about a speed run...
LOL apparently I thought I blew up one of the turrets but didn’t so when I reached the radio room I had to run back and destroy it so it took like 8 tries.
This video is a good ref for the general strat, sadly my most successful run got stuck at the second artillery gun. Sniper on the crane made me antsy about getting shot and I got pincer attacked.
