RavenIt is possible to conclude a surprising amount about the details of what the character Raven can do and about how Raven was made, if one pays attention to the manual, in-game videos, and Raven's capabilities in the game.
We know from the manual that he is partly organic, has superhuman reflexes, and that his strength is "almost five times that of a normal human." We also learn that he has a highly logical thought process, which he showed superbly during manufacturer's tests. These "tests" involved Raven killing real people in laboratory test ranges. In game play, we even learn that there is extremely thorough copy protection built into Raven, to prevent the making of more Ravens by anyone other than the manufacturer, Gyrex. The manual tells us that the Actuated Razor Crescent weapon on his arm is not actually physical, but instead it is a self-contained stable energy field that comes from a projection system mounted there, rather like a "lightknife" instead of a lightsaber. The manual also tells us that this technology has something to do with superconductivity, and further, the "blade" can either remain stable as a fixed weapon emitted from two points on the projection system attached to his arm, or this self-contained energy field (that has a sharp edge) can be fired with a flat trajectory. Or, the manual goes on to say that with technological improvements that are modular (power-ups), he can fire more than one of these razor crescents at the same time, even though there is only one projector on his arm -- as the technology that stabilizes the field becomes better. When fired, we are told by the manual and by in-game experience that the crescents are accurate and perfectly quiet, even at impact. Noise comes only when people cry out for an instant as they are hit by the ARC. The manual says that ARC technology was originally developed for medical excision of cancer cells, then from its effectiveness was extended to mining and construction use, then to combat uses.
We know from the intro video that he has no reproductive organs and no mouth, so he can neither talk, nor ingest, nor breathe, nor compromise himself by talk or sounds of breathing. We know from gameplay, however, than he can still send and receive all kinds of information with a built-in communications system, even though he cannot speak. If he cannot ingest, he must not have an excretory system, either. This suggests that whatever his unspecified power storage mechanism is, he is equipped with the technology to convert directly back and forth between energy and organic molecules, as with the Borg (trademark) in Star Trek: the Next Generation (trademark). If this were not so, there would be no way for him to get these organic molecules or get rid of waste. We know he does need to do this, and has organic parts, because the manual refers to splicing things into his genes, which means that he has genes. In the intro video, we are even shown a diagnostic display of his brain, which looks as though there are significant organic parts that remain. The video even shows us the system of cams and gears that enable movement of his pelvis and his legs. We are also shown a graph over time, which proves by pictures that he grew from a baby, with internal organs, etc. And, of course, the most disturbing evidence of a partly organic nature is that if Raven in killed in battle, a large amount of blood spurts from his collapsing body. For evidence that it is not necessary for him to breathe in order to survive, it can be seen in the game that if he is immersed in water, he is incapable of drowning. Instead, he can swim around indefinitely with no ill effects. Logically, he must have a crush depth, but it must be extremely deep. And though he has no mouth, we can see from the intro video and in the game that he does have a nose. His nose appears much like that of a human. A nose would be militarily useful for Raven, especially if we suppose that Raven can use his nose to perform superhuman feats of tracking and hazard detection. Since we know that he cannot drown, it follows that he must be able to close his nostrils whenever he wishes. From the part of the game box cover that folds open, we know that Raven's eyes have serious technological augmentation. A diagram there reveals that he has both infrared and ultraviolet vision, besides the normal spectrum. In gameplay, there is no way to shift vision modes like this, but there is a sniper zoom mode that can go all the way up to a factor of sixty-four. Of course, this is very useful for observation, for killing by head shots, and for choosing an unexpected firing angle to go through tiny spaces between obstacles.
From gameplay, there seems to be no limit on the distance that Raven is able to fall straight down, while still not being injured. Logically, Raven must have a design limit for this, but it must be that that limit is simply not reached during the events of the game. At one point, Raven is shown leaving a dropship that is hovering very high in the air, after the ship had transitioned down from orbit. Raven has no parachute or analogous device. He falls in a standing position, assumes no special posture, and does not roll, and yet he hits the ground with no bounce and no impact mark. Indeed, he is operational without any delay, proceeding as though nothing had happened. There must be a truly astounding shock absorption mechanism in Raven's body and joints. Further, the intro video shows us that Raven has an artificial "hyper-spine," in which points of articulation are shown to be more numerous than a normal human would have. Another reason why this makes sense is because he is able to turn his upper body so quickly in game play when he uses his ARC blade at melee range. His whole upper body then rotates in a reflexive snapping motion with great force and speed, producing a scything effect that can kill more than one close-range opponent with a single blow.
