Leviathan – Resistance 2

The Chimera are usually thin, skeletal creatures, but the Leviathan represents the raw power of the alien race. It swats helicopters out of the air with ease, its ghastly face filling the screen as it picks you up in a deformed claw. Fighting it is a mess of explosions, collapsing buildings and plenty of rocket launcher rounds fired directly into its gaping maw.
