Part 4:
"Usas la M-15" is not translated.
At the very beginning, go west, and when at mountain wall with huge closed stone door, you can select to go "East" and "Este". "East" will give you the GL264 code from the Dome, while "Este" will make you go east.
There should be an inscription on the stone door, but I can not read that in this version, maybe because "Este" is in the menu instead ? - is this the numbers needed for the reinforced door ??
The code is not the date: 25/2, it is not the year: 82199, it is not GL264, and it is not the code for part 4.
There is no other numbers... if there is, where to look for these ?? - please explain / give a hint, so I know the numbers is not missing because of a bug, then I will test the rest of part 4...
Part 5:
When using the M-15 you will always get the message that there are 0 bullets left, but there is bullets left, you will first have 0 bullets later after shooting a couple of enemies...
Epilogue:
Leslie: "....her eyes looked at me with vitality and I knew then that she had saved my wife" <-- should that not be: "...I had saved my wife" ???
