Great Content, Great Storyline, but lets evaluate the actual Gameplay.
REUC attempts to replicate HOD arcade shooter using the Wii Remote as a light gun, but falls dramatically short.
The first area in which it seems to fail is the target response. When firing at a zombie, you can't just shoot any part of the zombie, it has to be an area that activates a glowing cursor. If you fire anywhere else, your bullets will go right through them. Then if you do contact with the target, the target reacts only 50 to 60 percent of the time. The other 50 to 40 percent the bullets seems to go right through the target as if you did not make contact.
The real flaw of this begins to appear as your character travels through the level. Based off of traditional light gun shooters, you have no control of your characters movement through space, but much of your character's movement seems to be timed independent of your actual interaction with the targets. So instead of waiting for the zombies to be dead, many times your character will keep moving even if you haven't hit a single one. So it doesn't matter that 50 percent of your bullets some how phased through your target, your moving on anyway. But then you come to the moments where you do have to actually eliminate your enemies to move on, and the target response inconsistencies become overwhelmingly frustrating. Each zombie will wind up for an attack which is completely uncounterable once they reach a certain point. Leaving your bullets all the more worthless.
In combination with your character's independently timed movements, the targets and their inconsistencies make for a feeling of uncontrolability. Sure the story is good, and there are numerous secrets and unlockables, but once you look past its loads of content you realize that the gameplay is just spinning your wheels.
