Weaponized Mob Arena

This arena features complex controls for difficulty, item drops and even falling lava blades. Other features include semi-random spawning and floor traps. Made in 1.2.5, tested in 1.3. Play alone or with friends; there is no real goal besides survival. Ready your blades!

NOTE: make copies of the save when you download it - the only way to reset the map is to reinstall it.

Starter chest is located outside.
