Awesome! I'm so glad you got it working and beat it! I don't see a lot of people beating the map, great job. Yea it took a long time to make but was fun making and testing it. Did you happen to figure out the golden spork side easter egg? Or find the song for the map? Or find the funny jumpscares at the lighthouse?

I did find the Golden Sporj Easter egg, however we didn’t find the other 2. Perhaps I’ll have to go back and find them

Hello! The map worked for my friend after what you told me could help and the two of us spent hours playing the map and completed the map!   
Screenshot I took of the win:

If I were a map reviewer I would rate this map 10/10 for how much creativity was put into it, I can't imagine how much time was spent creating this map. It just has that nostalgic feel of mob of the dead but even more was built off of it. I think my favorite bosses were Brutus and The Dark Rider just because you actually have to take them on yourself and you never actually know if or when you will go down but you keep trying anyway. The Easter Eggs on this map are absolutely insane and are so cool when finally completed, well done on this map Whippy well done.

I'm sorry to hear that. I've been experiencing some texture streching too on several maps. You can try changing your texture setings to Manual in your graphics and set them to either low or medium, maybe high. Then apply amd restart your game. Changing that from automatic to manual should fix it. Just make sure it saves in your settings when you restart your game. See the problem is the T4M .dll file that allows maps like Alcatraz to be played past Cod Waw's limits. It has a bug with streching textures and that is the way to fix it. I hope that fixes it for you. Have fun

Thanks so much for the response, I'll have him try what you suggested 

Hello WhippyTrout. My friend and I want to play your alcatraz map together so badly, but we are unable to because his just won't work correctly. My version works perfectly fine but when he tries to play he loads in with lots of fps lag and his games textures start stretching and bluring, becoming unplayable. We have searched up ways to fix this problem and none have worked. Ex: getting a new common.ff file, cleaning up the mod folder, to even using console in an attempt to do something. We want to ask you for a fix if you have an answer to this problem. Remember, the problem he is having is his textures and world stretching everywhere and freezing up his computer. I really hope to hear from you for a fix for this and thanks for reading!

P.S.: If anyone else has a fix for this it would be much appreciated if you could help us or state a fix as well!
