<P> Halo 3 : ODST is a shooter video game with most gameplay taking place from a first - person perspective . The game features an open world environment in the updated Kenyan city of Mombasa , referred to as New Mombasa . Although the gameplay of ODST bears a strong resemblance to that of previous Halo titles , the player does not assume the role of the enhanced human supersoldier Master Chief , protagonist of Halo 3 . Instead , the player controls human soldiers known as `` Orbital Drop Shock Troopers '' or ODSTs . Since ODSTs do not possess the Master Chief 's advanced armor and reflexes , they can not jump as high , move as fast , survive large falls , or wield two weapons at once . Instead of the Master Chief 's damage - absorbing energy shield , the game uses a recharging stamina mechanic . After the player sustains damage , the screen flashes red and the stamina score decreases . If the player receives additional damage before the stamina can recover , the player 's health is reduced . Loss of all health causes the player character to die and restart at the last saved checkpoint . Medical packs scattered around the game environment can restore the player 's health . The player 's head - up display ( HUD ) includes a `` VISR '' mode that outlines enemies in red , allies in green , and items of interest in either blue or yellow . </P>
