There's just a couple of variables to set it up however you want it. One is that, when you touch your flag to return it, you actually pick it up and have to take it back to the stand yourself. This means that, in bizarre standoffs, one player can actually even end up with both flags in their possession. Another is that you can change the time that a flag automatically returns so if you make it something longer like a minute, it'll usually give players enough time to grab onto it again.
Not a great mode for maps with insta-death floors or voids, but fun on most other maps. Definitely a change of pace on the traditional formula that raises the stakes for defenders and mid.
