When playing as Grant, his objective is to navigate through seven areas of Isla Nublar, and make it safely to the Visitors Center to escape via helicopter. However he must contend with the various dinosaurs that roam the island, now free of their enclosures. Grant can use various weapons, including a tranquillizer gun, a stun gun, flash grenades, gas grenades, and a rocket launcher. All of these items require ammunition refills which are scattered throughout the island, sometimes in hard-to-reach places. Grant's recovery item is a first-aid kit, a few of which occur in each level.
