This is the best use of an OPK.

[hihiman1]

The best use of an OPK that you can do is Quarantine mode. You guys probably already know this but ya. You dc then infect all the humans in the tower, or while you're a human you can dc then knife the infected in the head for 10 seconds and bam rc and he's dead. Do this at the very start when there's only 2 and you won. Or if you wanna be discreet then knife the zombies for only like 8 second for both of them, and then it's only a few more shots to kill them.

Both are really fun.

Excuses for the opk
_______________________
Human killing infected:
- ur an idiot how didn't u see me knifing u for like 10 seconds?
-infected:how did u kill me?
human : idk i guess you had little life left
alt. : y r u asking me?
alt2. : I knifed you

Infected infecting humans:
(You should only do this while they are guarding those doors that lock.)
Best excuse and the only one you will ever need
- I came from left side, you were all looking other way lol.
If they say that they were guarding left then say:
- right side w/e
This is good because there is no way for them to see both sides, and every one knows it's possible for the infected to go to tower in like 2 seconds if they sprint. The only way for them to really know that you're lying is if they ask their teammates that were guarding the other side, if they say that you didn't come, guess what you say?
-Then they're blind
Then the opposite team will think that they're stuck with noobs

THIS IS NOT OPK OPK STANDS FOR ONE POSITION KILL MEANING U KILL FROM 1 POSITION

WHAT U HAVE IS CALLED TAPPING A CRUDE METHOD AT CHEATING IN ONLING GAMES.

AND ANOTHER THING MAKEING ALL THE PLAYERS FLY IN THE AIR OR UNDERGROUND WITH NO WALLS (LIKE WITH FLY HACK) IS CALLED SVP SNIPER VANTAGE POINT NOT OPK
