The level and sound design also complimented the oppressive atmosphere. Levels shift from tight corridors to larger, more open rooms that are usually indicators that your about to engage in some serious combat. The music is genuinely brilliant. It tries something completely different by having a futuristic score, using mostly synthesizers. This synthesizers go from relaxing to utterly panic inducing, when enemies surprise you.
Speaking of abilities, Prey features skill trees, which unlock powers and passive abilities, again similar to bone runes and whale runes of Dishonored. There are three separate trees to upgrade, all offering their own unique playstyle. These playstyles are coupled with levels that can be approached in a variety of ways. In the demo, one room could either be escape through exploring and finding a keycard, or through the use of a vent.
The weapons also seem as varied as the levels and abilities. There are, I believe, five that can be found in the demo, a wrench, the gloo cannon, stun gun, shotgun and crossbow. Each has been given the sci-fi treatment and made to look futuristic. The gloo cannon goes beyond use on enemies as it creates solid blocks that can be used as platforms, which I then used to access the upper floor of the level. I hope to see more weapons with utilities like these, as it would add to the open ended nature of the gampeplay.
Enemy design is also underwhelming. All enemies are essentially black goo in various shapes, although they do have different abilities. These enemies are more annoying than fun, thanks to these abilities and the ineffective weapons. The mimics, which can transform into any inanimate object around the level, are especially annoying due to their tiny size and attacks in numbers. Maybe combat will improve as weapons and abilities are unlocked, but I don't see the frustrating nature of combat being sorted out.
The combat, the main focus of the game, feels frustrating since none of the weapons offered offer any kind of satisfying feedback, outside of the traversing levels. Hopefully the full game improves on the combat through upgrades, however enemy design remains weak.
I would still recommend checking the demo for Prey out. The first hour is filled with intriguing moments that are, hopefully, more representative of the final product.
