Tom Clancy's Rainbow Six Extraction

• The goal in most situations is not to trigger alerts. An alerted enemy will start to gather up energy Goku-style and then release it to trigger an alarm. Killing them before that happens stops the alarm.

• Using silenced weapons in almost always the right choice.

• Smoke grenades and later flash grenades make for easy melee takedown.

• Don't be afraid to extract if things are going to hell.

• Playing solo is viable, the enemy count scales well with the number of players.

• The usefulness of the starting drone is marginal but the auto-scan drone you get later is excellent.

• Don't take ops that aren't at full health.
