The map seems to favour defenders a fair amount. If they have their wits about them, a good defense can control almost all of the nice items - the armor, the rocket launcher, the railgun, the regeneration, the megahealth...leaving basically the quad for opposition. By the time you cross the large map any powerups you got from your own base are all but finished. That requires you to have a well coordinated offense, with numbers a fair bit larger than those dedicated to d - not neccessarily a bad thing.
Unfortunately, the bots on the opposing team )this is why I want humans( decided to all but turtle. This map makes that way too easy :-( Any attempts at offense were easily squashed, except for one: Take the upper route, grab the megahealth just before you jump (the bots are too dumb to control it), and then tele back up with the flag. And this worked 99% of the time (when you could get that far into the base). Once again kind of whacked out balance.
However, in the last 5 minutes the bots decided to cooperate. They left a few people on d and mostly went out hunting. I called a few bots to follow me, and many interesting battles ensued (as many as 5 minutes can alot, really). 1/2 of the capping was done in those few minutes. So with agreeable players, it can be lots of fun..but otherwise, good luck.
8 from me.
P.S. Er, the "multiple routes" are true enough, but there's only really two ways into each base without fancy jumping - one up and one below. Another chalk up for the defence.
