its a bit like a tug of war, except pushing not pulling
both teams can win by pushing it to the opposing end. while very good for comp play i personally dont think it will suit a pub. as cold said, it would be very stalemate. well, at least 80% of the time. it needs a lot of organisation and most players attempting to push at some point. a lot of pub play people like to DM it too much, meaning; the select few that do push become targets with very little protection. the cart would barely get out the central area, and, once it does the following areas are 'indoors' and very tight. one demoman in comp play can be stopped, 4 or 5 in pub play, and a good sentry, would kill it.
it is a very nice map none the less. it just isn't suited to large scale pubs. that's my view anyway.
