Basics

Open Your Eyes
When you're seamlessly being shot at in the dark, by all means do not just sit there and get pelted with bullets from every direction known to man! Simply switch the type of goggles you're using between normal vision, night vision, and your trusty thermal goggles. Thermal goggles will detect any body heat in the vicinity, so use them when you're being assaulted by an unseen foe to spot them out right away.

Barking Orders
Throughout your trip through the missions of saving presidents and killing terrorists, you will have a squad of supporting characters to grind away at the enemy troops. You can give orders to these characters to defend you, go on the offense, and much more. These orders range from assaulting the enemy's human arsenal to going through in recon mode to scout ahead. We'll give you some general direction of how to have your crew succeed throughout the walkthrough, but keep in mind that this is your adventure, and you should play as you want to.

Capturing
Throughout your adventures as a member of the Rainbow squad, you will come across items such as briefcases that can be "captured." This will help you along your way, as it unlocks hidden things within the game. Look alive, people!

Save Frequently
After getting through a really tough area in the stage, make sure to save your game. Since you will start out at the exact same place as when you saved with the same amount of health, be careful of where and when you save your game, as well. It might be best to take cover midway through a rough spot to save your game in a different file so that in case you die, the battle is half over.

Two of Hearts
One of the new gadgets that will certainly come in handy while sneaking around or simply preparing for battle will be your handy heartbeat sensor. By pressing the Heartbeat Sensor button, you can penetrate walls and other solid matter to find heartbeats. This will allow you to determine how many enemies you will be facing without going in to find out. Prepare accordingly!

Send in the Troops!
One of the most important aspects of having a team to control is using them to save your own skin. Sure, it may be sadistic, but you can send your team in alone with every gruesome scene to scout the area and clear it for your own greatness to walk across. To stay sharp, however, we recommend tackling certain areas with 1-4 enemies all by your lonesome, to keep your mind going. But definitely send your squad into any situation where there are tons of guns firing in your direction.
