Arena_mach has been updated to version 2, now called Arena_mach2.  This fixes many problems some people had with the map.  It now conforms to the traditional arena style of next to no health packs.  Some obstructions that hindered gameplay flow have also been taken out.

FINAL 2.0 CHANGES/FIXES:
-Logs to each sniper deck removed
-Boxes in the middle removed due to their placement being annoying in terms of movement flow
-Middle tower health pack removed
-Medium base health packs removed
-Both sewer small health packs removed
-Planks added to allow easy crossing from stairway base exit to middle area, which helps avoid sniper fire
-Spawn points fixed to prevent players spawning on one another

Damn...i happened to like the logs
Kept it from being a sniper/RJ class fest.

Maybe a bridge coming down from second level

I think it's good to preserve Mach4's gameplay because it's a good thing.  The log was a nice idea, but it just doesn't work that well in that small of space (it ruins the ability to move around at all there).  Plus, the "flag" area has a nice ramp for someone like a spy to come kill the snipers even easier.

Thanks for removing the log. It was a bit of a nuisance only because it seemed to be right in the direct path to the right entrance of the base and rocket jumping from the battlements to the middle elevator was awkward with the log yet alone having to walk around it when near it. Removing the health packs is also good due to the map being so small, and people were able to take over the middle with all the health packs.

I like it!

I always figured this was more of a d/m level anyways!

Great lighting!
