Alien Earth

One day life on Earth would change forever after an alien vessel crashes onto the planet's surface.

As the military quarantines the area and investigates on board, they'll discover all manner of alien creatures locked on board, each with different biologies and from different worlds. Of course any information onboard the ship is completely unintelligible to humans, being written in an alien language unlike anything on Earth, while the creatures on board all seem very intelligent, with thinking and problem-solving abilities comparable to humans, albeit with unknown goals or motives beyond escaping their confinement. There's no telling what would happen if they manage to get out, or what the humans in charge plan on doing with them...

(feel free to come up with whatever designs and ideas that you want for them. A few I have are an electric jellyfish-like creature capable of killing a man by both strangulation and electrocution, as well as manipulating electronic devices; a lizard-like creature that can blend into its surroundings, cling to walls, and possess sharp, venomous fangs and regenerative abilities; a small, slug-like parasite that can take control over a host body after climbing inside them; an amorphous blob-like creature capable of slipping its way through the smallest gap, altering its shape and 'digesting' any organic material it absorbs, living or otherwise; and there are likely many more horrors on board with various unknown capabilities and intentions)

(It is unknown whether these aliens were innocent victims abducted from their homeworlds by an unknown alien race for research and experimentation, or if they were criminals back on their respective worlds that were incarcerated on board the ship before it crashed.)
