This is recreation of ascension from black ops, that I uploaded over year ago to minecraft forums, but I decided to upload it here also.
This map has
wallweapons
pack-a-punch
working landers ( buttons in places, where landers should be.)
hidden song (requires editing resources file and sound mod enabler mod, to work properly.)
working traps
working perks
cave spider spawners that gets activated once in a while (can be disabled from spawn room)
Mystery box
zombies

Traps, landers and some of the perks requires power to be activated

I will add more details for this map later and thinking of adding some kind of wave system.

If you find bugs, or have suggestion, what to add next, then report them to me.

More details and older downloads can find here:

Additional Notes

Map doesn't require any mods to work, but I recommend using mods that disables creepers damage to terrain and endermans ability to pick up blocks. I also recommend using sound mod enabler, because without it hidden song won't work properly.
You should play on normal difficulty.

Latest version of this map requires minecraft 1.4.2
