I use the MP5 more than any other weapon. It dominates the HECU guys for me, and I play on hard difficulty. Make it any better, and I’d barely use any of the other weapons.
I definitely agree about the drowning speed though. I set mine so that the player loses 5 health at a time instead of 2. Maybe Gordon drowns unrealistically quickly this way, but it certainly makes underwater sections more interesting/fun (and lines up with HL1 and HL2 standards).
What happened to the military taking over the announcement system? They have a weird announcement in We’ve Got Hostiles that changes from the Black Mesa female announcer to the HL1 style male announcer halfway through (somehow), informing everyone that the announcement system is now under military command. But then they just stop with any announcements at all. I loved how in HL1, from that point on, you’d hear the military using it. They’d sometimes even try to trick isolated scientists into reporting topside for “questioning.” Brilliant stuff, but nowhere to be found in Black Mesa…
