Add in the ability to combine
vehicles — like a
military Humvee - style jeep and an ATV — to create conveyances
of carnage and it's not uncommon to rack up zombie kill combos in the
hundreds or even thousands.
You can browse the internet (a parody
of it), buy and sell stocks, hike, sail, fly, rob banks, punch people, steal
military vehicles and invest in real estate or you could just drive (following traffic laws if you're really that bored) and visit the
hundreds of stunning locations in Los Santos and Blaine County while listening to the various radio stations.
