Not much information is known about it, apart from it being an ARPG slash Tower Defense game, but screenshots look good, so I caved in and pre-ordered it. Anyone else here getting it too? I'm a sucker for pre-orders though, so this is more of a stab in the dark with me not knowing anything about the game.

It looks just like Dungeon Defense, one of the showcase games on the Unreal Dev Kit site. I guess this must be an full-blown expansion on that, the way World of Goo and Portal were on their respective precursors.

It looks like fun, and the price is good. I see it's marked as "DRM-free". Does anyone know if GamersGate's definition of DRM-free is actually DRMless or if they're pulling an Impulse on us?

If you buy on GamersGate, do you have to download anything just to be able to download the game, or is it as easy as it is here on GOG? Because there's like 4-5 games over there that say DRM free and I want them. I need them.

Something similar to any other tower defense system? Sign me for beta tests and warn me a week before the premiere' so I can preorder ;)

I pre-ordered it pretty much the day it went up for pre-order. I'm sucker for dragons though. There is a sort of demo version available in the form of an early alpha build prototype to show what they *could* do. You can find that on the UDK site IIRC (it has a slightly different name and is totally lacking polish, but it still gives a good idea of how good this game *could* be). It was enough to persuade me to order anyhow. You download the GamersGate downloader (which is specific to the game you are downloading). All that is there for is to help manage your download and it allows you to pause, stop and resume downloads. It also acts as the launcher for installing the games.
If a game is listed as DRM then it has no DRM on the game. However, the GamersGate downloader will need to connect to the internet to confirm that you have purchased the game.

However, during installation if you navigate to the numbered directory within the GamersGate temporary files directory, you should be able to copy the unencrypted setup.exe file to another location. Once installation has been completed, select to keep the temporary files and copy the setup.exe back. Then you can install the game on another PC (one without a net connection for example) without needing to be online.
That does not work for all games though. And that would be the early build prototype I was talking about.

Checkout their Ask a question thread for a list of questions that have already been asked.

Short version: Try the prototype, then get the full version. ;)

It's definitely DRM-less. You need to login to download the game and install it. Supposedly once downloaded, you still need to login to install the game, but this can be circumvented, which means that if you buy from Gamersgate and they say it is DRM-less, it is as good as buying a GOG product.
Thus far I've had no problems backing up my games without authentication. Not sure if the inability to circumvent the procedure is only present in high profile games like EA's, but I've checked about 70% of my games, and none of the 70% prevented me from backing them up. Perhaps you can ask around first to see if a particular game can be backed up. The game is really low profile though. I hope it picks up on publicity soon.

Yep. I think I first heard about it from GamersGate's Tweets and looked into it. The prototype is a lot of fun and the Unreal Scripts are also released for it, so if one wants to install the Unreal Development Kit and extract the "source" into it, you can make modifications and then play them.

Ex: Tweak the crystal's health, make the mana coins hang around longer, etc. Pretty neat to see the level lit up brightly with mana coins. :P

(10 Oct 10) Edit:
Bummer. Instead of releasing on the 1st of Nov, it's looking like end of November instead. From what I hear the progress made in the demo carries over to the full version, so it won't be a total loss. :|
