I think you can remove Wall Weapons from the Box... With that we can get Different Set of guns from the Box... I take option 1. 

Time for UPDATE 3:
New shots:

First, all weapon chalks have been redrawn, they now glow correctly and face the right direction.
Some water in the map is still unfinished, hence the PAP picture having no water at one edge (and Ill leave you wondering how you get there )
Lighting has been massively improved, but still needs work

Mapping itself is about 85% done, features not so much

And lastly, I am starting to make Double PAP guns, only 2 done so far though, and please feedback on the camo, Should I add some metallic purple aswell?

Anyway thanks for all suggestions so far, Keep em comin'!

Looking reaaaaaally good!! And since it's an island with underground stuff, why don't you call it lost emergency base.

lol, reminds me of that bit in pirates of the Caribbean where Jack and Elizibeth are stuck on an island

"Why is the rum gone!"

Nice, looks fun to play.

i like the look of this so far

Just tested the map co op and have a few problems
Default weapon is in the box
When another player fires a PAP weapon, everyone can hear it as if it is right next to them.

Mapping is 98% done now, Just need to add final touches of detail.
6 Double Pap guns done now, more will follow
EE song added

I would put the Wall weapons out of the box instead of keeping them in the box to put an answer to your question
Suggestion for map Name:
-Stranded Deep
-Deserted
Question about EE song: is the song Copyrighted?

The wall guns ARE out of the box, and im in the process of adding more to refill it. (With double PAP versions)
The song is Carrion by Kevin Sherwood (TranZit EE song) Im unsure if its copyrighted or not, if so it runs on the music channel so it can be muted in game

Default weapon - either your loading a weapon but theres a problem with its model, or youve included one of the default weapon in dlc3_code.gsc

Pap sounds - Youll just need to edit the soundalias in weapons.csv, but if your using the deault one, it should already be set up correctly

UPDATE

Fixed a lot more bugs, more double pap guns added, new camo added.
Map detailed a little more.

One more bug though, but heres a new screenshot, so I can show it:

The ammo counter is slightly cut off the bottom of the screen, Im using DidUKnowIPwn's custom font if that's important, but if anyone knows a fix let me know

here's another shot:


The map is ALMOST done!
All double pap guns are done
Mapping is 99.5%
I just need to polish off the map, wait to hear back from beta testers and finalise everything.
You can expect release within the next week

Double PaP camo looks smexy, who made that? 

Trying to add little touches, game over cameras are giving me unhandled exception and out of memory error, not sure how but I am AT the weapon limit with double pap, so game over cameras will have to be removed

drop a sound or two, that saves tonnes of space

You can comment out pretty much everything in weapons.csv
