Lockdown?
10 crowns says that its gonna be some gametype with keys in it, like a harder version of capture the flag, capture the key! Each team has x number of keys that open locks on the other team's side of the map, you can either steal their keys or take yours to them, but if you hold a key, naturally, you cant fight, so the question is guard the keyweilder, or bring another to help facilitate the game faster, get greedy, or fight to play it safe. This is just speculation, and a bit of wishful thinking (also not an actual bet, but if im right... whoop whoop whoop whoop whoop!)
what do you guys think this new coliseum game will be?

I would love capture the flag, but I want it to be a sprite. They are so cute.
I want to be able to fight other players using my equipment. Guild v guild or 1 on 1 would be great. Also maybe a mode that lets you battle without our equipment for a more fair battle. But it would be great to have both. This game needs to give us a better reason to fine tune our equipment sets. I'm Interested to find out what weapons would come out on top in pvp.

King of the hill is what I'm thinking.

Capture the flag would be pretty awesome. but regardless, I'd say it has to do with keys or switches, judging by the name.
@Hempist 1v1 is definitely way too cheap. Judging by the beta experience, it becomes first, who has a stronger antigua line gun, then who has less lag. Now, if it was 8 person FFA, antigua stuff is still somewhat cheap, but it becomes a lot more based on skill, and is somewhat mind numbingly fun.
I think King of the Hill would be awesome, also CTF (would be my 1st priority if I was the dev!). Find a game with PvP.. almost ALWAYS has CTF. Great classic game :D. I also do like the ideas of Capture the Key, but I like to attack when I have the flag, or shield.
What would you guys prefer? Click and return your flag, or it would return after not being picked up after 30 seconds.
Frankly, I like click and return, but that's my opinion. (Because people can suicide in your mob just to renew the time on the 30 seconds).
Also, I think rated guild pvp matches would be awesome! In more customizable guild halls!! (Hint hint** More customization in guild halls costs more CE and crowns, more money for you potentially OOO ^_^)

Spoiler: It's gonna be pretty cool.
Don't tell anyone though.
Uh oh! Spoiler alert!! But a good one :D Can't wait Cory

I dunno, Hempist. I fine-tune for T2 and T3 enough as it is. I think there would be an immediate and overwhelming majority of people who would hate the game to quitting if it happened. The groups of PvPers who think they're hot stuff in Bomb Network would get a serious wake-up call when the Ash Tail they're so proud of does them no good to a player who, like me, has several sets of fully-UVd 5 star sets and weapons to match, as well as a stack of trinkets in operation.
I'm hoping for vials and vases. Stun/Sleep/Freeze vials and fire/oil vases. I have no clue how to incorporate locks in my setup, but I'll figure out a way.

It's also *much* different from Blast Network.

Is it gonna be like block pusher? Trap the opposition in squares that you push around on a bomberman style grid? It was my first guess.
I hope it's more puzzle based, less "quick reactions" based, and doesn't get old so fast, because I can see blast works becoming a sort of ghost town.

Oh man, Spiral Knights Trivia!
Also looking forward to this, hopefully soon, now the Devs got me excited!

Ikr, hope it isn't based off of something I already play >_>

lets just hope its better then Blast network.
Maybe you'll have to fight people who complained about Blast Network. :D

Hahahaaa, nice. I'd take that as a blow, but a funny one. That would be great though, seriously.
I'm pretty attached to the idea of a King of the Hill minigame. Or a defend the base/attack the base challenge.
The name reminds me of my favorite Halo map: Lockout.
I was also thinking some kind of Capture the Flag thing, someone else had mentioned something called Domination which was similar in aspects. I didn't think of the key idea though so thats something.
