That is Water Slide map mod for Grand Theft Auto IV. Slide have 23 objects and it is positioned in Alderney. You need to use this with your mates or simply alone in SinglePlayer.
Press M+Num four to start out Ragdoll, then simply use WASD to manage your participant. I examined this with my mates and so they stated that they see this so your mates see this too, however should you wanna be certain you may give this to your buddy.
