I was tooling around in INF trying to figure a way to override Stand-Off and I have succeeded-to a point. Set everything the way you want in your TDM, but set the time limit as 0. Now matches will go on as long as you have enough reinforcements before you bite it for good. Now be sure to set the Last Player Standing timer to something reasonable or you're going to spend a lot of time yelling at your bots to find one another. I'll post this in Troubleshooting too.
