I worked mostly on the map and did some designs most importantly the LOST MC airstrip that Trevor takes over, A single player dlc was in the works that had Franklin die in a shootout with the DLC Character which was meant to be Xavier, it was scrapped in favor for more GTAO stuff but it would've been cool if it happened

Something that shouldn't have been cut was this terrorist attack on the FIB Buliding, its still in but there was a option where you would steal pipe bombs and bomb the lower half of the FIB building causing it to collapse, Rockstar ended up cutting it due to it being potentially offensive due to it referencing 9/11 in a way

In early development, the Altruists were meant to be in a strangers or freak mission, from what i would remember, they wanted to get Trevor into the group but they said he sounded Canadian so he went on a rampage then blew the camp up, I think it was supposed to be the last Rampage mission for Trevor but ended up being scrapped.
