So, I decided to post this because I get tired of being shot. An easy way to work together. This takes it beyond a run and gun or the annoying "STICK TOGETHER!!!" strategy. A few tips on how a "SWAT Team" would handle room clearings, hallways, and open areas. An easy way to think tactically. It's a little slow going but you survive. This also really helps in expert.
Now, clearly, most people will just hope everyone else follows them. Some will read this and think it's a boring way to play. But, I'm pretty bored now so.....yeah.
#1: No one should be looking in the same direction and scan your area. The direction of their gun can tell you where they are looking. If you enter a room, open area, or hall whoever is First usually tries to blindly progress thru the map. I like use this to my advantage and use them as an unwitting pointman. The Second should be looking in any other direction than the First. Third then covers the Second's rear and so one. Obviously SWAT Teams will already know who goes where prior to entering. You can call it out as you run through the maps too. But, keep in mind your team probably isnt going to designate a "Pointman." So it is important to pay attention to where another is looking, then enter the room, because you can still cover them from the door way. SWAT teams generally have a rule, "The First is always right." Meaning even if First calls left and goes right it doesn't matter. Second adjusts to First because First may need to act on a threat or be blocked somehow. This eliminates friendly fire, and needless damage from commons.
#2: You can see in the rooms, clearings, or halls before you enter. When applied with #1 this is a great advantage. SWAT Teams even have all kinds of nifty methods for this. An easy one is when First is on one side of doorway and Second opposite first, Third in middle, and Fourth covering rear. In halls Third and Fourth can cover First and Second's back. First and Second can scan almost the whole room forming an X with their line of fire. This can be done very quickly or very methodically. Think of another method as slicing a pie. This is done with one person at the doorway and all others still looking in opposite directions. Or second covering First and entering after while applying #1. The person at the doorway starts at one wall and moves to the other in a half circle away from the door. Again, very quick or methodic. This provides almost an entire view of the room as well. There are a ton of different configurations with four people and most of which can be utilized by one person to look into/clear a room.
3# Moving around can be tricky when one bullet seriously injures/kills your team. Typically a good formation for L4D is a line with space in between players while applying #1. First covers front, Second left etc. Again, SWAT Teams have a ton of formations to move safely. When passing rooms, openings, or halls that don't need to be entered just glance in. Second will see First engage and can cover. If First does not see a threat that is there, Second can step in and the threat has usually already commited to First. Giving Second an opprotunity to engage in relative safety.
Most do not understand this stuff. But, if you do you can adjust to at least one player while applying most of these principles and they won't even know. You will find that just by applying #1 your friendly fire rate drops significantly. #2 will primarily be done by yourself in L4D. Get on the wall outside the room, open area, hall and clear all that you can see. Then "slice the pie." https://www.youtube.com/watch?v=K5OctwulUiMhttps://www.youtube.com/watch?v=wXiGvHI2_So
