Omar Escort - Dead Island Side Quests Walkthrough - Act 1
This escort type quest is unlocked after completing the Hit and Run quest, also given by the same NPC, Omar Torres
Talk to Omar Torres in his bungalow. He will express interest in joining the other survivors in the lifeguard tower.
Your goal is to follow him and protect him from the zombies. He is not killed easily, but still the mission can fail if you let too many zombies get near him.
Try to stay as close to Omar as you can. If you lose him, find his marker on the minimap. A good strategy in this quest is to stay a little ahead of him, killing any threats before he gets to them. If the zombies manage to kill him, the mission fails and you have to start over at the save point.
When you finally reach the lifeguard tower, talk to him to get a experience bonus as well as a nice revolver (it has limited ammo so use it carefully!)
This completes the quest.
