The favored mode of exploration is the guided walk: Lemarti or his Samburu cohort Boniface, armed with only a spear, leads visitors on journeys that can last from two hours to five days.
The experience went from one of exploration in the tech demo to one of gimmickry in TF2 -- the game's VR Mode is little more than a new window for viewing the game, and has almost no impact (at least in our demo) on gameplay.
