Call of Juarez: Bound in Blood

Playing as Ray, in the large square where you need to catch up to Thomas and before William runs up to you (checkpoint) make sure that you charge up (but don't use) your concentration mode. Run to the checkpoint. A cutscene plays with William running up to you. Run around the corner to face the snipers and enter concentration mode. There are three snipers that you must hit. Tag them and exit concentration mode manually and you can kill them all before Thomas gets off a shot.

Throw dynamite on top of the building. There are 3 enemies and you should have at least that many bombs. This way is recommended if you forget to charge your concentration mode which can be annoying.
