I already typed a big introduction to another my submission in GameBanana so I will be short
This map is a half-remake (i.e. fixed a lot of stuff and added a lot of features) and half-remix (from de_747 to zm_747) of 3D-Mike's de_747 for zombieGround.ru Biohazard server (46.174.50.62:27015). Hopefully you will enjoy it!
Please note that this map is intended to be played in the multiplayer server, some features won't work if you will play it in singleplayer. Also I do not promise stable work of this map on other zombie servers but ZombieGround.ru one.
