Decisions, Decisions: Better path
When playing the Decisions, Decisions scenario, when you have a choice between going to floors BF2 and BF4, choose BF2. You may encounter Hunter Gamma, but if you go to BF4 you will encounter Giant Wasps and Giant Spiders, which can be a burden while you get constantly poisoned.

Decisions, Decisions: Avoid getting touched by Thanatos-R
When playing as Jim, you can do a nice trick when fighting Thanatos-R. After using the Daylight anti-virus, you can Play Dead (R1 + Circle ) and avoid getting touched by Thantos-R. Use this when you are hurt, to avoid getting attacked, or make your teammates mad in an online game.

Decisions, Decisions: Avoid Sharks
You can avoid Sharks on the pier by running tug against the railing. The Sharks only appear on the non-railed side.

Decisions, Decisions: Save ammunition
Do not waste ammunition on Thantos; he is invulnerable. Run instead.

Shock Thantos with hanging wires to obtain the T-blood rather than trying to take him out with force.

Decisions, Decisions: Getting a weapon with Alyssa
In the beginning of this scenario, Alyssa can be the first person to get a weapon. In the Elevator Passway, there is a locker protected with a simple lock. Use the P shaped lockpick on the locker (easy, normal, and hard difficulty settings) and you can get a assault rife or a handgun. Under the very hard difficulty setting, you will only get handgun bullets.

Hell Fire: Defeating final Boss
When playing the scenario, the final Boss is easily beaten if you continue shooting at her with a weapon such as a handgun or shotgun; or by throwing concrete pieces at her from a safe distance. Your teammate(s) will take care of the other Lickers.

Hell Fire: Avoiding damage
When playing in hard mode, avoid opening Room 201. When you do, fire bursts out and damages your character.

Hell Fire: Save ammunition
Use Concrete pieces instead of wasting bullets.

Hell Fire: Grenade Launcher and AntiVirus (L)
When in room 303, there is a wall that you can take down (in between the plant and the bed) by tackling or shooting it. In there you will find a female corpse with an Anti Virus (L) and a Grenade Launcher with Acid rounds under the window.

The Hive: Getting to the rooftop
Go to BF1 and enter the room near the gate were the zombie breaks in (the open one, and not the one that you need the keycard for). Go to the computer and enter 0930. When you get in the elevator, you can now go to the rooftop.

The Hive: Save ammunition
Step on Leeches (R1 + Down + X) instead of wasting a bullet. Try to avoid the Leech Man, or if you have low health and/or you are bleeding and he charges at you, tackle him or use a Scrub Brush to push him back.

The Hive: Leeches on computer
In this scenario, there are Leeches on the computer. Rather than wasting three bullets on them, tackle the computer three times or use the Scrub Brush to knock them all off together.

The Hive: The Giant Leech
Certain weapons deliver more damage than usual to the Giant Leech Boss. These weapons are the scrub brush, spear, and broken crutch.

Outbreak: Extra gun and ammunition
In Scenario 1, when you get the R.P.D. "SWAT car", after you get out, go back in. There should be two shotguns, three cases of shotgun shells, a magnum revolver, one box of revolver ammunition, and some handgun ammunition.

Earn more points at the end of stages
To earn more points at the end of stages follow some of these steps:

No Damage Clear: To get a "No Damage Clear" do not get attacked by any kind of monster. If you come close to a monster, use your special attack (R1 + X) or ram the monster (R1 + Circle). When a monster is coming close to you, call for help (Right Analog-stick Left) and the CPU character will arrive to help. If done correctly you will get about 4,000 points. Note: This is not an easy task. It is recommended that you play the game a few times then trying for a "No Damage Clear".

No Weapon Clear: To get points for a "No Weapon Clear", pass any weapons you find to the CPU. You cannot use any weapons/ You can pick them up and combine items for the CPU, but you can never use a weapon. You can use your special attack (R1 + X) and the characters will punch or kick the monster. You can also ram the monsters (R1 + Circle) . You also can use health items if needed for you or your CPU characters. Note: Only Kevin, David, Mark, and George can punch, kick, and tackle.

Obtain all items: To get an even better score, obtain all items in the stage. You must collect files, useless items (such as diaries and test tubes), press buttons, etc. This will boost your points. Note: Collecting the items can clog up your inventory spaces. You can pass the items to your CPU characters to keep until the end of the stage.

Obtain the "Daylight" virus: In the stage "Decisions, Decisions", collect an extra tube of "Daylight" virus and you will get a different ending and points. Note: When getting the extra "Daylight", do not use it. Keep it in your inventory for the different ending and points.

Stopping your virus meter
There are two ways to stop your virus meter from going up. The first way is to use the Anti-Virus Pill. This will stop the meter until you are attacked again. The other way is to use a Red Herb. This will stop the meter for a few minutes.

There are more ways to stop the virus meter. You can do this by using any healing items (for example, First Aid Spray. Green Herb, Recovery Pills), but it does not stop as long as The Anti Virus pill.
