Looked at the Rockstar Newswire for this and someone said they 'snuck a peek at the trophies'
"3 Blind Mice- Blind 3 players simultaneously with the pepper spray.
Sweaty Betty- Trigger & avoid a Bouncing Betty by shootdodge.
Betty Confetti- Kill a player with the Bouncing Betty.
Resisting Arrest- Stun 10 players with either the Cattle Prod or Stun Gun.
Breaking & Entering- Open 15 containers or doors in Dead Men Walking.
It Looked Easy Enough- Complete the Challenge Mode.
Breaking The 4th- Earn a X4 multiplier in Challenge Mode."
It was some random in a comments thread so keep that sodium on stand-by.
Those items. :/
I was content just to get the co-op DLC but when the whole shebang is 1200MSP? They might have got me.
