When I was 11, I played Team Fortress 2. 1 year later I wondered how they built the maps. I looked into it and found that they use the Valve Hammer Editor. Ever since that day I started to make maps.
This is my first map I've been working on for a while. Me and my friendly Andrew have been working on this for 2 days, and yes we are new to the modding thing. If you see any flaws let us know in the comments, and if you think this is a good start share it with friends!
