When surrounded by dinos such as dilophosaurs, raptors, or pteranodons, try hiding your back. Retreat to a wall. The flame thrower is useful because you can turn and walk while shooting. Sometimes this ability of the weapon can save your life. Note: The flame thrower will not blast pteranodons away if they started a counter-attack. When you have a moment, use a weapon that throws raptors and dilophosaurs at the ground, then for another moment you can deal with only the other enemy. However, this works only if there is just two attacks. You can also use firewalls, but they are really not that effective because of their short lifespan.
