DM-3rdspacebeacon is basically DM-2ndspacebeacon Second Edition. Bertoid lists all of the changes in the readme file for the level, so I won't go in to them here. If you haven't played 2ndspacebeacon, then here is a BRIEF description, as a full rundown of the level would take up about 35 hard drives. You are on a space beacon that is INCREDIBLY LARGE for a beacon. There are many structures outside and there is a complex sewer system on the inside. You can snipe from everywhere almost, there are MANY z-axis opportunities (outside the complex there are about 5 "stories" of buildings plus many objects that extend far above the complex.). There is nothing wrong with this level architecturally or otherwise: except for playability. The size of the .unr file for this map is 14 MB. This map is huge. Gargantuan. It is smaller than 2ndspace beacon (but only slightly) and there's a BIT less curved architecture so the polys go down a little bit but this map is still really unplayable. Bert says in his readme file that he has a few 800mhz machines at work that can take this level fine. I have a p3-600 and I am constantly stuttering when entering new areas of the level. Sorry Bert, we don't all have 800mhz machines so I have to deduct points. Don't even try this level on less than a P2-400 mhz machine.

Not much else to say here - it's a good level if you have the horses to drive it.... it should be a 9 rating, but that playability factor really sends the ratings down the tube.
