Sanctum is the world's first FPS tower defense game and is set in a beautiful science fiction world. You take the role of Skye, an elite soldier sent out to protect her hometown, Elysion One, from hordes of mysterious alien creatures. To facilitate your success you construct defensive structures and upgrade handheld weapons. Jump right into the fray and wreak havoc with your own weapons - unlike regular tower defense games, you are a key part of the defense. Sanctum has taken the best features of first person shooters and tower defense games to create something totally unique.

I feel like buying the game... Just for the Yogscast DLC XD
Had hopes for this game, till you started doing DLC.
Are there any chances for more free updates? I like the game a lot guys, but any new content outside of two maps has been pay only.
Now it is available for Mac on Steam. The field "platform" should be updated.
So the beta is only new stuff if you have Mac?
I find the creators of this game very inspiring, as when I'm older I want to take up game making as a possible career/hobby, as I've wanted to do that since I was around 5 years old. I'd also really like to know what game engine they used to make sanctum, because I think the graphics are great! So, as I started with, I find the creaters of this indie inspiring role models, and hope to turn out like them one day!
Also, if the dev's get this comment, I would really REALLY appreciate some basic tutoring towards game making! :)
Sanctum is made using Unreal Engine 3.
The best tip if you want to start making games is to grab some user friendly tool like Yoyogames.com and try doing some fun things.. The second thing you need to learn is to write code :)
It is awesome to hear you get inspired! :-)
