Despite my low opinion about polymer, I'm actually played this map back when it was released, and replayed it now. Well, speaking of design - I can't say that its the best space base level, but it looks good, although outdoor areas oblivously the worst parts of the map. What I really liked about the map is the abundance of interactivity, i.e. objests that you can use and which is not a generic buttons (trhough it's really a hidden buttons ). In almost every room there's something you can press, and it's something that we don't get that much nowadays. There's also a lot of jokes which is really funny, like a viewscreens in the beginning). Monster and ammo ratio is OK, except of the annoying turrets. Laundry is something we don't usually get in a space maps, and sewers is nice a change too (am i the only one thinking it looks too Earth-like?). I also love the ending, which is simmilar to Maarten's Unknown Planet ending).
With all that said, it's really a good, even revolutionary map, which will sure inspire me when I try to make a space map.
