PL is 4 before powers. It will jump to 5 once you get powers.
The island is a small-sized (about a score miles long and a half-dozen miles wide) isolated tropical paradise in the Pacific. It has lots of jungle and mountainous terrain and lots of beaches and crystal-clear waters. Used to be a military facility in the early Cold War (though few know of that fact) that has been abandoned for a good forty years. It got turned into a massive tropical resort American-style only in the last three or four years. There is an old village to the north since its first settlement decades ago - small brick houses and even smaller port, no more than a couple thousand people - with an old lighthouse as its only landmark of note. Most of the island's beaches sport extensive hotel complexes that act as centers for the island's nightly parties, having all the dance floors, cinemas, restaurants and bars and shops and other forms of recreation but only about a third of the island's visitors actually live in those complexes. The other two thirds are spread in bungalows and small motels, camping sites and very authentic (not!) colony-style farms all over the island, where visitors can enjoy the "wild" and "natural" side of life without being too far from the comforts of civilization. A much smaller part of the population can be found in the island's one ski resort, on the slopes of the island's tallest mountain, overlooking the island's east from two miles up. The only two ways to reach that ski resort are the three aerial tramways connecting it to the three biggest hotel complexes and a tortuously steep and hard path through the mountains. The only installation higher than the ski resort is a large array of radar dishes dating back to the 60's, part of the now-abandoned military complex (which few people know about and even fewer care) overlooking the resort from a good half-mile higher, well into the islands' perpetual snow zone.
The zombies you'll encounter will come in several types, most common (and usually least dangerous) of which will be the slow zombies. You will encounter more than zombies though, in the typical Resident Evil fashion - though less "biochemical nightmare" and more in a "supernatural evil" kind of way. And the powers you'll gain will be tied to this, of course.
The powers you'll gain as soon as the intro is out will resemble (but not be the same as) various legends of evil/undead creatures you may have heard of so consider what flavor of powers you'd like to gain. Ghoul, vampire, loup-garou, wraith, wight, banshee and the like are all good flavors/inspirations. That does not mean you'll actually be such creatures - only that your powers will be similar. I want to keep the "how" and "why" of you gaining powers as a secret for now though you can plan on the "what" you want to gain of course.
