You'll be behind the controls of Laverne now, and there are a couple of things to keep in mind before you go forward. First of all, you've got a UV Turret that'll fry any Kryll that attack. Simply sweep the ray over them and they will burn up. Second, you need to know that the vehicle has a rather limited energy output. Therefore, it can only divert power to the engines or the UV Turret, but not both simultaneously. Luckily, the Kryll come in sets, so you won't have to constantly be on the lookout for Kryll at different spots. The white meter at the top of the screen represents your vehicle's health.
