Being watchful
Pay very close attention to your team If you see someone doing odd things such as not shooting at enemies when they appear or moving rather far away from you when your walking be on alert as this could be a sign of infection However do not waste a Blood Test Kit on him to see if you are correct Just be on alert because they could mutate at any second This also goes for you as well if your team sees you doing the same things they will question your trust and may attack you
Blood Test Kits
Save Blood Test Kits for showing your team that you are not infected to gain trust Using them on a team member is useless because they get infected randomly and usually break out within a minute of infection
Defeating the final Boss
Go in the helicopter When the pink tentacle appears from its back pump it full of lead Then hit the mouth part When you get knocked to the ground or near it blow up one of the barrels and watch it burn Repeat this until an intermission sequence starts
Defeating the second big Thing
Go into to his garage Fix the electrical panel that operates the hoist Step back towards the middle of the big door There is an opening between two of the crates Using your grenade launcher in first person targeting send in a grenade If the Thing turns its head toward you then you have him targeted Continue sending in grenades until he begins to burn You can send in a few more if desired for extra fun Run into the Things room and on the far wall from the big door is a switch Throw the switch and watch as the Thing dies You will probably take one hit from him
Defeating the third Boss
Run around the Boss in a circle while shooting it with the machine gun When it is low on health use the flame thrower to finish it off If done correctly you can kill it without being hit After you kill the Boss the Thing in the glass in the room will break out and the door will be opened with a few guards
Flamethrowers
Never give anyone a flamethrower Not only can they accidentally toast you but it seems to give that person a higher chance of turning into a Thing Even if you have more than one flamethrower do not give an extra to someone else

Variants
Take a couple steps back before pushing the engineer through the door and run at him Instead of pushing him all the way into the room youll go through him and he will stay outside but his face and gun will be visible through the door and hell still attack the Boss briefly
Also if you do this the door may stay open for the cutscene during which the engineer will attack through the door When I did this he had a shotgun and you could see blood spraying from the back of my head with each shot during the cutscene but it did no damage to me Not sure if having the engineer attack during the cutscene does damage to the Boss
