Someone requested me to upload the map as a standalone file, without all the command blocks and here it is!
You also need the resource pack for the map to look like it's supposed to, keep in mind though that many of the assets in this resource pack are not mine, I suck a pixel art and so I took some assets from some old gun mods and copied their textures, I also found some skins and transferred them into armour making some edits here and there to fix it. The only assets from the resource pack that I made are the thunder gun, the zap and wave gun, the ray gun mk2, the space helmet overlay and the barricades.

Also, if you want to make this map functional, use it on a server or anything along those lines, feel free to do so as long as you give credit :)
