Yes,but only online
You can play 2 players
Nope.
2 players
you cant get an airplane on saints row 1 only in saints row two
you can get it in missions or you can do a cheat (saints row two only) so dont keep on trying in saints row 1
Unfortunately you cannot, if you look at the back of the case it says "Players: 1" but you can do a system link and play up to two players.
saints row 2 does not have 2 player mode but it does have a co-op mode thats online that you could play with your freinds or with other players in playstation network or Xbox live
There are five currently, Saints Row, Saints Row 2, Saints Row: The Third, Saints Row IV, and Gat out of Hell.
They removed them from Saints Row 3. You can only get them in Saints Row 1 and Saints Row 2
Not only is Shaundi indeed in Saints Row IV, you actually get two versions of her, her modern day self and herself as depicted in Saints Row 2.
Saints Row happened in 2006.
Yes, you can just play co-op. :)
