Bland, huge areas, mostly full it, poor item placement and typical Italian emotions in E1M9 because the author could not accept criticism. I think we have come a long way since the troll wad era back in the 2000's, me included. The Gamarra series is pretty much a long forgotten thing over 10 years later.
Great '94 map. Don't be discouraged by the seemingly impossible scenario the map starts your w/! There is a secret area that will allow you to activate a crusher that'll kill the cacos in the first room.
Once you get past that first tense section, the map really opens up. There are some toughish fights in this map, but nothing too frightening - due to the lack of Doom 2 monsters.
The gameplay in this one is superb, check it out! Really surprising how well put together it is, seeing as this one came out before Doom 2 did!
A very detailed (but nearly microscopic) techbase map.
The detailing is quite good - truly feels like a real place.
Gameplay wise, the map is too small to offer much of a challenge. It took me under 3 minutes to UVMAX. I enjoyed what was here, but really wanted to see more.
