Hey Matt, im KEY (solomolo1677)

I absolutely love your work. the map is next level. far better than any other custom map i've ever seen. i could imagine this as a fun DLC by treyarch if they had ever been in touch by the Alien isolation team. i love everything, all the details.

i have a few improvements that you can implement if you might be interested but it's also an idea.

the map is hard-ish if you don't open everything before zombies get everywhere so i would say increase the prices of doors to make it even harder to make it more challenging.

I would say reduce the amount of wall buy guns a bit to challenge the players. you could also possibly add one more location for the box to go to to make it more challenging for the player.
since the theme is space stuff, i would say (if possible) reduce / remove older guns for normal zombies and keep the more futuristic stuff that kinda matches the theme. like the thundergun is amazing. but an old PPSH is not really to the theme, still just an idea

you could possibly add a bit more locations and unlockable rooms that the players could explore. make sure to keep the prices for doors high so that the player has to work for it and watch their points. the reason is so that for the player to reach the end, they must have collected enough points before they escape that they have at least got to round 20. this is for difficulty and time sake.

I do own the actual Alien Isolation game and the graphic are 95% on point. the atmosphere, the sound everything is great. i don't know what else you could improve there. maybe darker shadows for a more eary and scarier theme.

Now, the fun stuff, the buildable stuff

since the Zombie Chronicles has moon and space suit, i would say have a buildable section where the players have to gather the parts and build the space suit before they escape through the airlock. also, since some areas of the station are damaged, maybe you could alter some stuff with the gravity to make it a little bit more challenging. the finding of the parts i would say also applies to other sections. so have like three separate places that the player(s) has to turn the power on for the master power to be on. in my opinion, the players could also find parts for the power to turn on.

for the place where the player finds the keycard, you could make the room behind it usable by putting the keycard there and having a little area of its own. also possible spacesuit part location.

the original game had a flame thrower, if possible you could copy a texture or make your own flamethrower.

you could also add a bit more training areas or move the objects around a bit so training is possible but somewhat difficult.

since the airlock takes time to complete, how about you make it so that it takes 5 min to complete and during that time more zombies spawn and they run faster and you could use the Mission 16 Music from the Alien Isolation game during that time.

you could have some easter eggs steps where if the players finds information and parts around the map to activate some terminals that have random numbers. these numbers could later be used to activate a radio which plays the recording of ripley's mother (blowing up of the ship in the first movie)

YOU COULD ALSO ADD RIPLEY's VOICE to the main character.

i understand that this is all extra stuff but i truly believe that this would make the map insanely amazing and better even tho it is already amazing at V3.0

looking forward for your V3+ update :)
