Honestly it's pretty damn good, but the author seems a little too up himself..
Edit 5 years later: I seem too up myself for leaving this comment, how ironic
This is actually a pretty fantastic E1 themed map, you could swear this was made by Romero himself, for the most part. "Deathmatch the way ID did". It's too big - You'd want 4 - 8 people here, but it's very competent technically speaking.
Map05 is the only one that looks decent for deathmatch, otherwise this mapper showed a lot of potential for SP/Coop mapping, with these large creations.
Looks like a fusion of Greenwar map01 and that one map from SwarmDMx. Theyre both great maps so I'm sure this would be too, for duels that is. Keep it up.
