If you were a nostalgic fan of the franchise then you would’ve pre-ordered, it took a whole two seconds to do so digitally.
For players that either didn’t know or didn’t have the means at the time, you just have to accept the fact it was a missed opportunity.
Like another person pointed out, some people took the pre-order opportunity to buy several copies of the game with pre-order codes and are selling them for ridiculous prices on sites like eBay. This happens with every game that has pre-order content.
So, the secondary or gray market is your only chance of obtaining the ‘87 Jungle Hunter & Ole Painless skins. But be prepared to pay upwards of $200+ for not pre-ordering the game as a penalty.
In my case, not only did I pre-order the digital deluxe edition because I’m a huge fan of the films, but I literally bought a PS4 Pro JUST to play Predator: Hunting Grounds. I’m an Xbox guy and haven’t owned a PlayStation since first generation.
