Warpath

"A long, winding road connects the bases of two teams. To win a round, your team must capture all five command points in sequential order. Walk over a command point to capture it for your team. Once it has been captured, a panel covers the point for 15 seconds, briefly preventing the other team from recapturing it. Work as a team to take enemy command points, and prevent them from breaking through the front line to capture your points."

This is a great map because it involves a lot of teamwork, it is best to have a couple of engineers to cover the command points when you capture them.
As of yet I have found only a couple of tricks for this map.

Build SG on Command Points 2 and 4

Medic!

Use an EMP or grenade if your brave enough to get to the roof, now set up a Sentry Gun on the edge. A dispenser will also be needed as this location is very open.

Help Team-mates into the Enemy Base

Heads up!

While some of your team will be attacking from the front and distracting the enemy, crouch here and it will allow a surprise attack on the enemy defence hopefully securing the next cp.

Blue Base Map Glitch

Argh glitchy!

Near cp2 make your way round to the slope heading for cp3, crouch and walk into one of the joins in the wall. You will drop into a small gap.

If your still confused check out the bigger screenshot or demo.
