(Before you download read the description) An arena which contains 6 waves that gradually increases in difficulty. (No it isn't the full map of final sin and I wont be planning to do it either.)
New update out now! go download the new file here (Mediafire.com)
I've made not too many changes but I removed some monsters and extended delays. Most notably, it replaces the monsters with SwampyLad's DE enemies addon. Go download the necessary file here to load it properly (Moddb.com)
The map itself includes pickups that respawn with a cooldown, 6 waves that increase in difficulty and numbers. After beating a wave it will set a 30 second timer until the next wave starts. During the start of the game, you will be given access to all weapon mods and runes and make sure to equip them before the wave begins. Some parts of the map aren't as accurate as eternal since I have no eternal to use a reference with. You can ask me if there's any problem with the map. NOTE: This map will only work with eoa, d4 monsters, and de monsters so basically it wont work with other mods unless it has the necessary files needed.
To make it work, load with eoa eternal, d4 monsters and de monsters (Note: the file already contains the de monsters). You will have to get the eoa eternal file from the eoa server, though the file in eoae already contains the d4 monsters. William's monster pack can also work as an alternative for the monsters.
