The second The Predator trailer has arrived and it looks as though things are getting pretty weird down here on Earth. As if a regular Predator wasn’t dangerous enough, it’s time to genetically mess with them as well.

We’re still not entirely clear why humans would feel the need to mess with the genetic makeup of a Predator. Because a race that are nearly perfect killing machines really don’t need to be even bigger and stronger, do they?

Here is the official synopsis.

From the outer reaches of space to the small-town streets of suburbia, the hunt comes home in Shane Black’s explosive reinvention of the Predator series. Now, the universe’s most lethal hunters are stronger, smarter and deadlier than ever before, having genetically upgraded themselves with DNA from other species. When a young boy accidentally triggers their return to Earth, only a ragtag crew of ex-soldiers and a disgruntled science teacher can prevent the end of the human race.

The Predator will hit theaters on Sept. 14.
