10 OBVIOUS Video Game Plot Holes (That Actually Aren't)
6. Crysis 2 - Why Nuke The Ceph When They Are Invulnerable To Nukes?
You would think that, when facing an alien species possessed of superior technology that humanity would be careful with what we throw at them. In Crysis 1 the military launch a nuclear weapon at a Ceph ice shield only to find, to their dismay, that the shield expands, proving that the aliens can absorb nuclear radiation. Despite this, in the second game the military again consider a nuclear strike.
This seems stupid.
It isn't.
While it is true that the Ceph are able to absorb energy, a nuclear bomb is not all heat and radiation. Near half of the damage done comes in the form of the blast wave, and at over 50 psi the blast wave of a 1-megaton nuclear bomb will demolish everything within a 12 mile radius (approx 20 km). Drop one in Manhattan and it will scour the island right down to the ground.
As shown by their vulnerability to conventional explosives Ceph are not immune to blast effects; if a grenade can kill them, a nuke will annihilate them.
We humans may be trigger-happy but without that science fantasy shield, aliens have little to hide behind - especially something as devastating as a nuclear bomb.
