1 player min

CTF
FACING WORLD
3 FLAGS
20 minutes
novice (bots difficulties
weapon replacement (use this to select your weapon of choice)
faster game speed (i forget the name for this)
start game
go inside of your base(where your flag is)
have your team hold position
then you are free to roam the map by your self without your teammate getting in your way.
try to grab their flag, and stay in there base and kill kill kill kill kill when they come in the door, and just kill kill kill with all of your weapon ( i think is 4 not sure)
after getting all the awards, have your team attack and capture all the flags.
Continue this until you get all the achievements.
= 4 weapons for match, after 10 match, you'll get 4 achievements.
*** please note, you can also get FIRST BLOOD, MONSTER KILL, HAT TRICKS, also working towards 100 CTF match.
This does work, this was my method.
Hope this helps.
