I believe that there are Steam gift cards available at GameStop. You can call the closest one to you to make sure if they have them or not.
Actually there are steam gift cards, but that’ll only help you if the shop nearby sells them.
target, walmart, game stop, and most malls have the steam gift cards.
Was that really necessary?
If the vents lead to ammo for the Shotgun, Magnum, Mp5, pistol, batteries and health, it might be worth it to put them back in
Yes, I do believe you can get a Magnum before Power Up in Half-Life
Well, the original HL 1 OAR was boring as hell aswell, but Text made something great of it (BM team already did a wonderful job by cutting it into a smaller map 
)
It’s not easy making vents interesting, in all honesty. The only vent I really liked was that padded one somewhere in Office Complex, it felt really cozy and I kinda just wanted to sit in there and wait out the disaster. 
This was probably my favourite chapter from the game I think…
It was very methodically done and the pacing was spot on…I don’t know if this really needs any alterations…???
although I won’t rule the idea out because I keep going back to this one again and again.
Let’s make a wide vent, then stuff a Bullsquid in there
that oughta wake you right up
Well, I started looking into the map using the authoring tools for Portal 2. It seems the map is kinda full on entities, so I might have trouble expanding it.
Create a new map? It’s only got 3 maps, I think. The only thing really “missing” from WGH was the vent puzzle, which you could fit in a new map right after c1a3c, I think.
Or, alternatively, edit the C map and put the some vents there.
Or alternatively alternatively, change the load point between A and B. Though that would require much more work, and I have no idea where you’d move it to.
Could work, though if the maps are already nearing entity limits, it’d probably be best to insert a new map instead of working with the limit.
I actually think this would add something…I can’t see why it can not be added at the load point after the marines rapelling from the osprey… There is no way the last map before going on to blast pit is full… All that would be needed is adding to the last map in WGH no more I should not think.
Reasons to do it…
The alarms and vox lines create a sense of emergency
It’s quite claustaphobic and would induce that the player is on the run.
Headcrabs dieing on the fan blades that got cut from office complex could be moved here instead…
And I also have another idea… Would this really be much work?
I doubt it but then again It’s easy to say until you start mapping it.
If you are going to go through with this project (which you should!), and end up de-compiling that map, you should consider putting Joel’s old version of the WGH theme (the less intense, more acoustic version) in the fight in the warehouse room RIGHT before when you go up in the freight elevator to the surface.(The room with the really high roof. I’ll find pics if needed.) The song is timed almost perfectly for that fight, and since the tune will be associated with soldiers, it’ll be fresh in the players mind, and when the elevator starts, and the intense version kicks in, it’ll create MAJOR anticipation!
I am not doing this…
The main reason is that it loads back to the first map of we got hostiles…
So it is too much work and I cannot be bothered…Basically if the last map would have been a new map then I may have given it a shot but because it means altering the first and third maos… Sorry not spending heaps of time on that
I actually did some poking around in the C map recently. It’s at around 92%. As opposed to A’s 180%. If there’s vents to be added, C would welcome them with open arms.
On that note, I also found out just how bad the spacial disparity is. Apparently the vents in C are five floors higher than their counterparts in A. Yuck.
OpenSource, I kinda threw together some tentative stuff on a vmf. I don’t know if you’re still working (or training for) this project, but there is that. If you’d like to see it I can send it via PM.
Going to throw this out there: if you have given up on this, I’ll do it myself once the Xen update hits. Or something like that. Maybe sooner, depending on how work on The Contract goes.
If no one’s willing to pursue this and you can manage it, go nuts .RK. Additional BMS material by way of more vent explorations would be welcomed. If you proceed with this, vent headcrabs dropping down onto the player from above always provides a delicious moment or two of fright and panic. Maybe you could consider an instance of a crawling half-zombie, provided he and his animations can be accommodated by a vent.
UPDATE: Sorry this project has been dead. I got a copy of Portal 2 in the end of July, & I got absorbed into some interdimensional outsourcing. Also, I had a lot of family stuff to take care of. I just got back from a Native American Dancing event last Sunday (I’m part Cherokee, courtesy of my dad). I also got The Orange Box & the Half-Life 1 Anthology Pack. I have been playing Half-Life 1: Black Mesa (the VALVe-made GoldSource version, not the fan-made Source Mod or the VALVe-made Source Port) & Team Fortress Classic. I also beat Portal 1. Also, I just Private Messaged you for the VMF file, .RK.
