Mix frustrating difficulty, tedious missions, sloppy graphics and a confusing premise and you've got Predator CJ.
In PCJ you'll play as the feared and respected predator, whose abilities are vast and unmatched by any other bounty hunter, mercenary or hired asassin of any type we've ever seen in the movies. The developers did a decent job of giving the creature some moderately cool looking attire that should be pretty reminiscent of what we saw in the movies. They also afforded the player the abilities to jump high and far, tear enemies up with lethal frisbies, spears and blades, (not including other projectile armaments), cloak, and use different types of vision to see different enemies or AI. So you're probably wondering why a game with all these goodies turned out so cruddy? It is because the predator's fun abilities are completely overshadowed by the games broken gameplay in a horribly conceptualized environment. It's just a pure shame that the character you play as will have several actions that at the beginning will mesmorize and intrigue you when you perform them. However, in the context of actual situations later on in the game, you'll find that these actions are downplayed, as the challenges they are required for are sometimes too difficult, but also just not presented well.
In PCJ, you will play as a nameless predator who is a member of some clan of other predators that set you out to stop the humans from using your stolen technology to their own benefit. You will have to kill gang leaders, police and anyone that wields a weapon of some sort to stop them. Initially, there is some confusion because though the movies never technically went out and stated that predators only kill worthy, lethal targets to collect honor (as opposed to unarmed civies), the notion that killing innocents will result in loss of honor. It seems as though some of the predator games just used this excuse to justify punishing the player for killing innocent people. You also will even help innocent civilians in times of need as they become victims of robberys and other activities, which is pretty irrelevant to the plot, and just seems out of place. You'll spend about 10-20 hours trying to get through this halfheartedly created story, depending on how good (dare I say, lucky) you are.
The game is just riddled with problems in the environment. Jumping from rooftop to rooftop seems incredibly fun, however it is just done horribly. You will often have to trial and error it when you miss a jump to another roof that you needed to get to to make progress, and thugs and people seem to find their way up onto roofs, which instantly takes so much away from the stealthy premise of the game. You also will find that the environment itself has cartoony graphics that don't sit well with a dark concept of you being a hunting, killing machine. If this isn't enough to make you irritated, the AL in the levels will be. Mechanically speaking, enemies and civilians alike just look bad. Civilians will get scared at the sight of you and simply run around like idiots instead of running away, and guards and enemies don't animate very well during combat.
The gameplay itself is frustrating and not well distributed in terms of difficulty. The first mission is a little tough but managable, with a few standard AI that shouldn't cause too many problems for you once you get the hand of the awkward control scheme. As you progress in the game, enemies difficulty increases about 5 fold. The problem is, you won't really be ready for it when it does. There is one level that is just a group of bosses you have to fight that are seemingly impossible to beat. I thought you were a predator! That being said, the game really could have benefited from the difficulty patterns being a much more gradual process.
Mission objectives are also a problem, as the checkpoint system pretty much just makes you start ALL OVER again if you fail something, resulting in pure trial and error frustration. You will do so much collecting of certain important items in the game that it becomes a tedious chore, and you will most likely just get sick of doing it.
PCJ provides a stealthy premise that while enticing in theory, just doesn't work at all in the game. People will still be able to see you whilst cloaked, and the mechanics of following someone closely behind while cloaked, so as not to get caught, and spying on people just don't play out smoothly. You will be able to use the cloaking on rooftops, or sneaking up behind people to execute them, but more often than not, you will get caught, and you'll have to just go in slicing and dicing as usual. PCJ also enables you to shoot people from afar using your shoulder projectile device which is also cool in theory, but just doesn't feel right.
The difficulty of the game overall is just atrocious, as many enemies in the later levels will be overwhelmingly high, or just respawn in areas you just don't want them to be in. This can be insanely detrimental to your progress in the missions, which themeselves are nothing to write home about. You will have to destroy heavily guarded devices, collect heavily guarded devices, kill heavily guarded people and sneak your way through heavily guarded areas. Though every misison tends to kind of throw something kind of different your way, that just means you will get angry in a different sort of way.
And don't bother with the challenge system, which involves you having to run through dull environments collecting items in a short time limit for no reason.
All in all, chalk this game up as just another neat concept poor execution, with almost no reason to buy it. Those who absolutely love the predator franchise could consider renting it, but should consider and take in all the game's flaws as a forewarning. If there is a sequel to this disaster, it better take about twice as long in the development stages as Predator: Concrete Jungle.
