If you can, absolutely play this with a friend. This was made for co-op. Each player facing a different angle, allowing for more ground to cover and being able to help out your partner if they are in need is amazing.
On-top of the dynamic co-op and the really solid gameplay, the overall plot, cheesy voice acting, and fantastic set pieces makes this imo a great light gun game with an action movie flair. Definitely a must play if you see at an arcade.
