Looking at cp_steel screenshots has gotten me excited for it. If done well it could be very interesting. You can see there is a control point E, so there's at least 5 points total. I'm guessing it'll be something like point A is required, then branches to point B, C, and D. B is required, but C and D only open up additional routes to E, but are not required to win. Then point E is unlocked when B is capped, and when E is capped, offense wins.
