Sergei survived hordes of those creatures, killed all of their leaders, even the "Yellow-Light God" but he was killed when one of the them hitched a ride on the roof of his mouth. How ironic.
the game itself is fun
but the ending sucks.
I hav an idea for the sequel,
earth is overrun by those creatures, and a small resistance is formed to fight them, there are more weapons, suits, even vehicles and turrets you can ride
