Custom win conditions?

    I've been trying to make a map recently, but I'm having difficulty setting it up properly.  I want the map to be one by capturing one point (for each team) ala steel or hydro, but not have it be a requirement to own all of the other cp's on the map.  I've been looking around on the internet and have tried to figure it out myself, but have been unable to do so.  If anyone could lend me a little insight into the matter it'd be greatly appreciated.

    As a quick second question- not completely neccisary, but would help greatly (if you can answer both questions, than only bother with this one, unless it gets too complicated).  Can you set the win condition to capturing two specific cp's?  I was planning on having the two unlock a third, invisible cp that would auto-win the game, like I asked about above, but if there's an easier way, please do tell.

Thanks for your time.

Yes, you can have a map where you only have to capture one point to win:

You can basically make capturing a CP do whatever you want it to do. If you want to have 2 CP's required for victory (two that can be captured in any order) you can use a logic relay. Have capturing one CP enable the relay, and the other CP can trigger it, which will then trigger your game_round_win entity.

(on second thought you may have to do a little trickery, having both CP's attempt to trigger the logic_relay, but then enable it with a 1 second delay, maybe there's an easier way to do it, but that's just off the top of my head)

Alright, and thanks so much for the help.

There's some sort of maths_counter entity that can trigger an event when it reaches it's limit. Using the cp's to add or subtract from the current count, depending on whether the cp has been won or lost, it can keep a tally of how many cp's a team owns, and end the round when one team owns them all. That would let you have as many cp's as you wanted, without having them in any particular order.
I'm not sure it's much use for a single cp though. I'd imagine that cp would only need to have a single output to trigger the game_win or round_win or whatever it's name is.
