Even then, Luke was still confident he could kill this second group of Predators, including the one in the cloak.
But this sort of risky action wouldn't have been worth it.
Some of the equipment on the Predators didn't look like cold weapons; there was no telling how powerful their firearms were.
The bomb which that cloaked Predator threw out at the end was proof of this point.
That tiny bomb was portable and easy to activate, yet it was as powerful as a nuclear weapon.
The other Predators had similar bombs on their wrists as well, which meant that it was very likely a regular weapon for them.
Earth's technology clearly hadn't reached that level yet.
If Luke had really fought those Predators, they might have detonated the bombs on the spot. He could've really been killed.
He would have thus missed out on a pretty good harvest! Luke subconsciously took stock of the items in his inventory.
