WHY??? why does this actually sound like its fun XD. +1 for a great idea.

@Leinhart: That would probably lead to players simply leaving at a point before it gets to hard. Wagering would be an interesting approach though. Similar to Krogmo bribes (at a lower cost), you can wager energy to unlock a bonus prize for reaching the next check point. The value of the prizes ramps up along with the difficulty, but there is always a small chance of getting a special rare prize regardless of current progress. This way, players can drop energy to maximize the chances of the rare prize, or hold off until the later stages to have a more reliable chance at a decent prize.

At some point the difficulty would have to taper off, and the gear upgrades simply become an even swap to change loadout. The Max level would have to be pretty hard, and NOT offer the opportunity to heal up like you can in arenas. Otherwise a group could carry on for as long as they can stay awake, taking the endurance challenge out of it and making it a perfect prize grinding game mode. A hard limit on HP capsules in the shop (if implemented) would likely need to be added as well.

Revived because this is a really good idea that I would love to see happen.

@ Leinhart, haha i was going to suggest exactly what you suggested in post #4 :)

Then i smiled when i read the thread and it was already suggested.
Sounds like a lot of fun. I've been calling for an endless dungeon since way back when!

One addition i'd like to suggest would be 'rare drops'. These drops you would start with when you played it again. For example say you get the rare drop "invasion brandish" (usable ONLY in zombie arena). It's a standard brandish, except now when you play zombie arena you start with your proto gear AND your Invasion Brandish!

Anyone remember lufia and the endless dungeon with the iris armors/weapons that worked exactly this way :D

+1 i like it good teamwork would result in alot of fun, it could turn out to be realy fun as long as this mini game has its own seperate currency and we arent useing ours to purchase it because one, people would farm it for coin, 2 it prolly be expensive to get better armor to go to next level so all im saying is seperate money thing maby like bones or something?

and if you get tokens for every round (dont make it easy) then you get token for every round complete and trade the tokens for some new type of armor and wepons?? maby ZOMBIE themed ^.~??
and maby like 500cr to play but only 500cr.. not 500cr per wave...

awesome just awesome

One thing to consider is that pvp in spiral knights IS a crowns sink. The winners make far less money than the losers lost, meaning every pvp match that occures takes crowns out of the system. This is a good thing as it helps control inflation. An individual can only profit in pvp if they are very good (having 5 or more wins for every loss in team matches) . PvP should be played for fun, and for the tokens/prizes, not for crowns profit.

This is pretty easy for the pvp matches, just make the winners payout less than what the losers put in. With this though that cant be done, there are no garenteed winers and losers, just the players and the feild, its esentialy non-clockworks pve. As such if you have a team that can make it to the profit point once, they can normaly do it any number of times, continualy putting crowns into the sytem.

With that in mind, I sugest puting the entrance fee to 200, in line with the pvps, put the break even point (the point were they would have made made their crowns back) fairly far in. Or even have no crowns pay out at all past the break even point, the rewards being purely tokens and entertainment.

And a leaderboard, have the teams that reached the highest round/survived the longest in overtime be displayed. Each week everyone on the top team gets a "you are awesome" costume set (which expires 2 weeks after you get it) and a decent token prize, and then the leader board is reset.

Not too original, but sounds good.

Ehh, not something I'd really suppourt, but I'd stick it in the game for a while as a test, to see how it worked out. Sounds fun yet it dosen't really make sense to be here. Kinda like bomberman IMO. Wouldn't make sense to be krogmo though, monsters are spectators.

Would overcome to problem of not having a crown sink, so I guess... why not? :)

With reference to Kimahso's comment, though, I'd say the originality may be something to worry about eventually.
I'm pretty sure OOO wouldn't be too keen on copyright infringement, but I suppose further ideas can be implemented later, once the basic gameplay mechanics are sorted out.
