Hey all just wanted to leave this information for those struggling with there 100 matches in this dreaded game, but have no fear I have a solution!
The way to get these matches played fast, and easy are by simply doing the following:
On any map, as soon as you spawn simply find an area where enemies will not harm or hurt you. Next, take your PS3 Controller and have something holding up the RIGHT analog stick thus making you do consist spinning circles. Then, just sit back brake out your laptop and wait for the match to be over. Rinse and repeat till you get 100 matches played! I can confirm that this will work 100 Percent of the time, give or take your internet connection. This is the only easy way to get this trophy while being able to multitask and do other things...
I hope this helps!
