This is an average Portal map. It contains three main rooms, ranging from easy to medium difficulty. There are no turrets, but the map still has some dangerous bits. This is a beta map!

I can confirm this one works in Portal 2 from start to end, if missing lots of textures. Modest and average, it's interesting to look back at the P1 default now and make comparisons.
