I've replaced current sound effects with high quality sound effects and added those cool items that does not appear in-game to the store.
Grunts now can be seen with scientist shades. (Contains Coolguys and goggles2)
Scientists can be seen with Coolguys and goggles2.
Restored one cool item that never appeared in game without any code left above apart from the stats to price and once name but a sprite. I gave it custom stats and price. It's $200 and i called it Science Goggles. (goggles2)
Zombie scientists can appear with the same armors which used by scientists in this mod.
And as an extra tutorial to edit your save game which means you can change your character to anything else. Or edit your inventory
But there is one problem. I added MAG sized PPK to store. But after buying it and going to main menu it turns into a regular PPK.
Funfact: They had spelling error in the description MAG PPK. And I've fixed it.
