It's not a straightforward yes or no. Some comic shops might offer discounts to attract customers at SDCC, but others might keep their prices the same. You'd have to check around to find the best deals.
Well, the Predator in the game is an extraterrestrial hunter. It's from a species that values combat and the hunt. They travel across the galaxy looking for the toughest opponents. In the game, when they encounter Aliens, it's a battle of two very different but equally deadly species. The Predator's story is about proving its worth as a hunter, using its advanced weaponry and stealth abilities to take on the Alien hordes and sometimes even humans who get in the way.
Predator and Alien were classic sci-fi novels as follows:
1 Predator (Warrior Series): Written by William gibson, it includes Predator, Alien: Contract, and Alien: Origins.
2 Alien (Alien series): Written by Ridley Scott, it includes Alien, Alien 2, and Alien 3.
I hope you like these novels.
