Infinite automatic pistol ammunition

The automatic pistols will collect ammo if you throw them down and pick them back up. Keep doing this to get 600 ammo.

Saving Medkits

Try to make a mark of some sort to lead you back to some Medkits that you could not carry before. If you so happen to run low or out of Medkits because of a big fight you can find them again. This is useful in Interval 11 with the armies of ghosts coming after you. Just make sure that you are able to backtrack to get the Medkits you left behind. Additionally, use your Medkits at the correct time. Do not use Medkits immediately when you have about 70 to 80 health remaining. Try using a Medkit when your health drops below 30. One Medkit can heal up to about 30 to 45 points. If your health happens to drop below 40 and you are in a 1v1 or 2v1 fight, do not bother using a Medkit unless you really need to. Just run to cover while using your slow-motion abilities. Your health will regenerate slowly back to 40 if it drops below that; however, your health does not regenerate during a battle.

Defeating Assassin Super Soldiers

Because the assassins are difficult to see due to their camouflage and high speed running, try using slow-motion (LB). You will notice them immediately once they are slowed and can then start firing at them. If you do not have slow-motion (for example, in the bonus mission when playing as the demolition man), you must have a quick finger and a good eye to notice them running around. There are two ways to do this. The first is to toss a grenade to reveal the assassin for a certain amount of time. Hopefully the splash radius will either hit him or kill him. Note: The grenade has a two to four second delay before exploding, and correct timing is required. The second way is to wait until the assassin is directly in front of you. When he reveals himself, start firing at him.

Finding Alma without her disappearing

During Interval 05: Extraction, reach the part where you are on the rooftops, with the ATC guards shooting at the extraction helicopter that Holiday and Bishop are in. One or few of those ATC guards carry an ASP (scoped rifle). Kill one of them and get the weapon. Save this rifle and fight your way through until you reach an area where you fall into a well placed sewer pool. When you are there, climb up the ladder and walk down the hallway with the huge pipes and the fence door that is ahead. When you get close enough to the door, you will notice something red standing behind the fenced door near the wall. Take out your ASP rifle and use the scope to check out the red object. You will notice that it is Alma waiting for you to shoot that lock off the door. She will not disappear unless you take off the padlock on the door or at least get too close to the door.

Office Space references in Interval 04

While making your way through the large office building, look for papers hung on the wall or scattered on desks. Many of these papers have "TPS Report" written on them, as well as a symbol including three boxes at the top. This is a reference to the popular movie Office Space in which the characters are involved with TPS reports at their office, Initech, which has almost the same logo as the symbol at the top of the papers.

While making your way through the large office building, about midway through the level there should be a large room filled with cubicles, with multiple offices on the side. One of the cubicles in the middle of the room has a lot of boxes piled into it, with a red stapler on the desk. This is in reference to the character Milton in Office Space. Management is always making Milton move his desk and using his area for storage, as well as stealing his red Swingline stapler. This can be found in the same area as the multiple TPS reports.

Shogo: Mobile Armor Division references in Labdog

After the firefight in the gas pipes area near the exit point of the map, there will be a gas pipe on fire. Turn the object off in the next room, then return to the now extinguished pipe area..There is a semi secret walkway there. Walk in, find the ladder, and climb up. You will find a health booster, and there is a door on your left. Go into that office. Listen to the song. It is the main theme from Shogo: Mobile Armor Division, an anime FPS created by Mololith. Look at the dry marker board. It is the same one from an office level in Shogo: Mobile Armor Division.
