Team Fortress 2/cp badlands

Badlands is a 2-way CP map with a focus on height oriented gameplay. While not as popular as some maps, badlands is still played often on many servers.

Spy
This is a great map for spies, providing you know where and where not to go.

A tactic often used is to disguise as soon as possible, then run out of the spawn and head right. Eventually you will reach the open area and the bridge; just before you reach the open area, cloak. Then proceed to the left-hand side of the bridge and run under it.

Crouch and walk to the far corner. Here, you will almost definitely not be seen. Now you can observe enemies attacking on the left or right of the bridge and charge them, or, once your cloak is recharged, head left up the hill and enter the enemy base.
