The Alien Fossil is a secondary objective found in all mission types. 10 must be collected in order to complete the objective.
Completing the objective gives 900 and 200 , which are both affected by Hazard Bonus.
Alien fossils appear as a fossil of a creature that seems to resemble an Ammonite, embedded in brown rock. The "creature" on the fossil can also be seen in the dark, although barely.
Fossils can be found in any environment. They appear on walls and ceilings, sometimes making their collection difficult.
