LOL the guy in the video is comletely wrong you can buy almost nothing in the Bazaar, just token trading and unique variant purchasing and unbinding stuff. Hall of heroes on the right is part of the missions segment and as you progress you go into hall of heroes again and again, and each time you get access to higher grade recipes for higher grade weapons and armour and shields etc. noob haha

Graphics: 8.5/10
I loved the Zelda feel it brought on the surface levels

Gameplay: 9/10
There is no "super weapon" and I can't think og any pay to win aspect since the PvP uses the same weapons you have. I also liked that you are limit to two weapons, a gun and a sword. Being able to make your own weapons with alchemy which you got from the dungeons was cool too.

Overall: 9/10
Spiral Nights is a fun dungeon crawler that feels like Zelda but delivers the CO-OP diablo couldn't all for free!

The energy problem is not a problem to me, you can use Ultimate Game Cards to get some or if you're just playing for fun you can just repeat Vanaduke runs to get energy or you could PvP and that doesn't cost any energy.

Love how I'm spamming the site today. :P Anyways. This game is pretty fun, people say it's like a mix of Zelda and I forget the other one, but. Graphics, music, gameplay is all good. It's basically just going into dungeons all the time though. Fun with friends, a bit boring when playing alone. You can buy armor, weapons, recipes and stuff. Bad thing about this game is energy. You get 100 mist energy which is the energy that doesn't stack, [and it takes about 22 hours to go from 0 to 100] and energy is used for pretty much everything you do. Still a free game, worth to play.

Even their site sign up does not work as it never sends the follow up email. FAIL

The energy system needs workin on, perhaps it could recover energy faster and hold more. also there should be other ways to get crystal energy (but not easy) otherwise you can only spend so long on the game till you have loads of crowns to pay the ridiculous prices for energy.

Meh. Not the worst MMORPG I've played. It's fairly fun, and it is best to have friends to assist you throughout the game. I'm DarkiaxHero if you ever see me. I dislike the energy system, as it has spiked to over 8k crowns for 100 CE, but it is a mechanical world after all. 8/10

I find this game pretty good, I don't see the energy system as a bad thing, you see, the key to this game is patience, and also the game is very short, lets say, if you have full 3* gear, and you buy some some CE (Crystal Energy, there's ME wich stands for mist energy, mist energy is free and it recharges in a total of 23 hours, CE is the solid version of ME, CE is used to craft items and buy items) you'll get 5* gear in one day, and the max stars are 5, so I think this game would be VERY, EXTREMELY SHORT if it didn't have the energy system, and there's a new mission, and rank system, I suggest you check this game out, but! If you don't like games that take time to get good at them, then don't play this, you'll hate it.

This game is Awesome, no matter what some of you noobs think. I know that yeah it might get boring after a week, but then when you get into higher levels and tiers, you can get alot more crowns and buy ce then keep playing, so rlly, the ce is not a problem. I have a 5* shield and 5* sword, and will soon have 5* cap and armour. Trick is to have really good pro friends, who can invite you to do a mission like firestrom citadel, then you can get 8k for only 50ce. My name is Lionkid in game, add me if ya wanna. I love the game, i like to play as much as i can, but dont rlly get on much. maybe around and 1-2 hours a day. The graphics are decent, and i dont know if any of you peeps have played other FREE mmo's, but this is possibly the best ive seen that you can play for free. A bit laggy though, which sucks... anyways Ima go to sleep now.

At first, I was annoyed by the energy system, but now I am fine with it. You sell recipes and gear at the AH for profit to make lots of crowns. You also focus on doing the last half of tiers. For example, I have made 7k-8k crowns by doing firestorm citadel while only using 50 energy. I like this game because it forces you to be resourceful and spend your crowns wisely. Great and fun game to play.

I thought I would reply with a few brief comments.

I have been playing Spiral Knights for about 2 weeks, maybe 3 hours a day. I've only crafted 3 star armor, and spent over $20US so far. You get 1 energy point every 13.2 minutes (full recharge in 22 hours) and completing 1 depth takes about 5 minutes, and 10 energy. Crafting a 2 star item is 200 energy, 3 star is 400 energy, 4 star is 400 and 5 star is 800. For 5,700 crowns you can buy 100 energy, but you do not make crowns fast enough to keep up with the speed at which energy de-pleats simply from playing the game.

When you die, you can have a party member resurrect you, or, you can spend 5 energy. Die again, 10 energy, die again, 30 energy, and then 80 energy.

That being said, simply to play 3 hours a day costs me $2.50 no crafting.

One of the most expensive MMO's on the market.

easy thing to say
+ more customization
- u need energy to play
+ u can play with more people
- people can just jump in in the games of that tire even if u are in the last depth before tier 2
+ much recipes
- u need energy (material = killing monsters = depth = dungeon = energy) to get the required material
+ much people use the auction house

so basicly is energy the thing that ruins this game a little

Great game, I love how the weapons level up rather than your character, so you are able to wield any weapon or armor you want with no restrictions but the availability of the equipment.

while this is one of the few recommended browser based games to check out, just to aware some folks that this game tends little repetitive when you have to go back to multiple dungeons and search for specific types of minerals, and items that will allow you to built new swords, shields, armor, and helmets survive any of the upcoming dungeons then do this all again.

As a game, it's rollicking fun. A bit grindy as things go on -- bring friends. Also: be prepared for the game to kick thee out on thy royal hindquarters. This is mostly due to the fact that game play literally costs in-game currency. As a result, it pushes non-paying parties towards casual gaming.

When you first begin to play Spiral Knights, it is actually quite fun. There seems to be many possibilities available to you, and many things to do. It is when you play the game for a week or two, that you come to realize of its flaws.

Graphics: A bit "comic-like", but quite decent for an online game.

Game-Play: Just like any other hack and slash game, but with a twist. Instead of just using a sword, you also have available to you guns, and bombs. Note, however, that you only have 2 weapon slots (which means you can only use 2/3 weapons at any time). If you want to get a third weapon slot, you will have to buy it with crystal energy, basically the "premium" in game currency (I have premium in quotation marks, because you don't necessarily need to pay real life money for it. It can be traded for crowns, which is the regular currency in the game, but the trading price is steadily increasing, and it is becoming no longer worth the crowns spent). There is no class or level up system in the game, and that is because you become your character by buying different weapons, shields, armors, helmets, etc. All equip-able items have heat (except for trinkets), that you gain from fighting monsters and passing through levels in the Clockworks (basically dungeons in the future). As your items level up, they become stronger and gain more benefits. There are also different elements, and resistances to different monsters and their different strengths and weaknesses. One weapon that's good against one monster may not be good against the next.

After a bit though, the game gets hugely repetitive. There are no actual quests, apart from the few that you get when you start the game (those aren't really quests either). All you do is grind and grind to find more minerals and materials. With materials, you craft new items. The items are rated according to a star system of 0 to 5 stars. The higher the star rating of the item, the stronger it is.

Final Verdict: Good game to waste a bit of time on, but gets boring fast. 3/5.

Quite Decent game. Graphics are not too shabby, Fast paced. A lot of Dungeoning. And no level system. Apart from a implemented "Heat" System from Dungeoning. Decent game 6/10. Recommended for all fast paced gamers.
