With Gun Showdown, we were lucky in that the structure was already pretty well-suited to "drop in, drop out" gaming. It wasn't hard to imagine that Gun Showdown would work well on the PSP. Long train journey? Play a story mission or two and advance the well-plotted narrative. Five minute wait for the bus? Play a quick side-mission and beef up Colton's stats. Gun was already a pick-up-and-play game but we wanted to build upon and add to this. That's where the new Quick-Play modes come in.
