Hint: Finding items and weapons
If you are having difficulty finding items or weapons, access the map, and look for the "X"s. They are indicators of where items and weapons are located. Sometimes there are also gold pickup spots next to the "X"s.

Hint: Double slash
Press Y to pull out the knife in a slash. Press RT to do a normal slash. Press Y, RT to make two fast slashes. You can also press RB to switch back to the weapon to enable yourself to double slash again. Press RB, Y, RT repeatedly to continue to double slash. This is very useful when there are multiple enemies and you want to rack up the dog tags.

Hint: Knife
Use your knife to destroy small encumbrances, such as fences, walls, snipers, or trees.

Hint: Power tool
The power tool can be used to destroy walls, bridges, trees, and almost anything else that can break.

Hint: Grenade launcher
Do not use the grenade launcher against people. It does not do damage unless it is a direct hit.

Hint: Better jumps
You can sprint after jumping. Use this to get more height and go farther when jumping.

Hint: Online tips
Use the following strategies when playing online:

When playing recon, do not be a selfish sniper. Stay relatively close to the objective. You will get more kills and your squad will not feel the urge to kill you as often.
When a vehicle or person is tagged by a tracer round, demo classes will be able to home their rockets in on the target.
Do not be so determined to get someone's dog tags that you forget about endangering yourself or your objective.
Snipers move; it makes it harder for a counter-sniper to draw a bead.
Never get into a helicopter without a partner.

Troubleshooting stats check bonus
Use the following trick if you are having trouble checking your stats on the website, which in turn will unlock one of the five bonus guns. Most gamers who had an EA Classic name are having trouble checking their stats and unlocking this gun. Even if your Gamertag is linked, it says that it is not. To fix this, login into the Battlefield website, then paste the following link into your browswer: http://badcompany.ea.com/myprofile/xbox/[your Gamertag]/

AK74u in Acta Non Verba mission
This weapon is a recon rifle like the SCAR. This means it uses hand grenades instead of launched grenades (of which you carry three more and can fire further). Once you destroy the missile launchers (the Armory objective), the Spetsnaz (Russian Special Forces), who attack you in their distinctive blue woodland camouflage, will have these weapons. Grab one temporarily, and add it to your collection.

M249 SAW in Acta Non Verba mission
This weapon is found at the beginning of the tank ride, in the first house on your right when you are ready to mount up. Since you will trigger the tanks to move if you go too far, you may want to finish the tank ride, then come back exploring. The large white X-mark will let you know which house contains the M249. It is useful to have when protecting the M1 Abrams in the town square. It is recommended you get this weapon before re-grouping at the red smoke after destroying the Zavrograd communications array.

SCAR (Silenced) in Acta Non Verba mission
This could be either the SCAR-L or SCAR-H (both can be silenced, they just use different caliber ammunition). You will use hand grenades with this weapon. The west side of the map has a broken bridge. Check the house just across for the weapon. Haggard will mention that silencers are for girls -- or for counter-terror units.

Gold Bar Locations
The gold bars are hidden at the following locations:

- Acta Non Verba mission
The house with the Legionnaire's insignia has a gold bar in the safe box. All gold bars will be in similar boxes.

On your way to the mission's second objective, there is a house at a fork in the road with some Russians. Clear it out, then check the second floor of that house to find a gold bar.

A gold bar can be found south and west of the Russian missile armory; there should be a small white X-mark in make shift pit (this is on the south bank of the river). It is the same location where Haggard says, "I smell gold!" (the beach camp with several Russians).

When destroying the anti-tank guns in the town, there is a building on the east half of the town with a red (not blue) "Hotel" sign. The building is defended by several machinegun nests (mounted and emplaced). You must clear the opposition first. Check the second floor to find a gold bar. It is one of the few houses you cannot reach the attic because the box blocks the ladder access.

After guiding the tanks, you will be told to regroup at the smoke. Instead of doing that, go left of the smoke, and case the wall. You will see the gold bar on a table-like object.

- Air Force One mission
Enter the building on the south end of the dam where trucks cross. It has two large boxes on the roof, and an SV98 and gold bar inside.

Enter the building where you have to destroy the radio equipment in the basement, in the room with all the explosives. The gold bar will be against the wall.

On the small island near an AA truck in the river, the gold bar is in the ruins of a small building that has no roof, with two enemy soldiers.

At the large base, after destroying everything and taking out the boats, look for a pair of two-story blue buildings. Next to them is a large white building. The gold bar is inside.

When you are sent out for fuel, go down the ramp. On the left will be a building with an "X". Inside is an RPG7 rocket launcher and gold bar.

- Crossing Over mission

Before attacking the first antenna box, continue east down the road to a construction area. The gold bar is on top of some cinder blocks.

After attacking the second antenna box, there is a group of houses down the hill. The gold bar is under the barn with the APC.

Directly south from third antenna box, there should be a house with an "X" on it. Inside is the MG36 and the gold bar.

While crossing over the pools in the walkway, look to the north to find some shipping containers. The gold bar is on top of the containers. Jump over from the nearby staircase to collect it.

After fighting through the harbor, go down the ramp, and turn to your right. Move in that direction until you see a small green house in the corner of the zone. The gold bar is inside the house.

- Par For The Course mission
Destroy the group of X spots directly above the west gun.

The island in the middle of the lake has a gold bar and an X spot with a collectible gun.

After you get the goggles and go to a weapons depot for some ammunition, there will be three tanks. The gold bar is behind the tanks on the golf course up the hill.

When you go around the mountainous rocks that separate you and the other pathway, you will reach the top of the map. At the tip of the map is an X and a tank. The gold bar is next to them.

A gold bar is at the rear of the mansion's bottom floor.

Easy "One in a Million" achievement
Play through a single player mission in Ghost Town on any difficulty. As you progress through the level, there are several opportunities for you to pick up the laser designator.

When you get to the last part of the mission, where you face the Legionnaire in his helicopter, use the laser designator on his helicopter. While the legionnaire is shooting at you, the helicopter is for the most part stationary. If you time it correctly, you should be able to guide the bomb and hit the helicopter. The easiest way to do this is to start locking onto the helicopter immediately after it shoots a few rounds at you and starts to fly around to get into another position.
