Chemical Factory v0.3 addon

Instructions:

This map is in alpha status and its my first map for Doom!!
There are some issues that you could encounter maybe..
For now its playable in nearly all difficult modes , tested normal Doom2 and Brutal Doom in any style.
Monsterbalance should be okay but i want response from you :)
Beside i want to notice... if you play easy... it will be easy.. ^^

Overall : This Map was made to training myself with the Mapeditor and standart settings (doom map format).

MAP Info:
Players: 1 (2/COOP)
Keys: 3
Enemy Count: 143
Secrets: 0
Items: 47
Average Playtime: 5-8 minutes on easy!
Boss: No Boss Monster yet
Buildtime for Map: Around 70~ Hours X_X (dont judge :S)
WAD needed: Only doom2.wad , no other custom wad needed
Engine: Any Engine that can handle jump/crouch , u will need it.

Missing Stuff:
-Its an 2 Player Coop available but not even balanced for it. (In mind , it should support at final 4 Players COOP with all stuff)
-Right now , there are Secrets but they cant be triggerd or be activated to 100% Score
-Secret Room is made but not findable without "idclip" , anyway this room is not even completed to show off.

MAP Story:

An Chemical Factory is overrun from demons.
Your Mission is... to shutdown the factory (there is an big computer control room) , clear it and escape!
Should be simple but be careful , the faster you run / the faster you could die in the darkness afterall...

Thanks for reading!
Feedback is really welcome!
