The result is an engaging storyline, fantastic, varied gameplay, and very few flaws to complain about. Brace for impact To understand and appreciate Oni you have to first accept the fact that the game is solely single-player. This is not your typical Quake or Tomb Raider clone. The keyboard is used to move directionally while the mouse is used to look around, punch, kick, throw, and fire your weapon. While alternative action controls are available on the keyboard for gamers who only use a one-button mouse, controlling the action this way is far more awkward than with a multibutton input device.
Level design is amazing, with architecturally realistic renderings of impressively large buildings.
At time's you'll simply wonder how Oni is able to be rendering the scene in real-time. Each level also has its own unique look and feel in regards to both design and gameplay. Level progression follows the general pattern of finding consoles to unlock doors while staying alive. A compass keeps you pointed in the right direction and allows the levels to progress at an enjoyably brisk pace. Advice from your teammates back at base in the early stages of the game further help you along, while passerbys in the later levels will also reveal tips and contributes to the story line, which is as captivating as one could ask for without return to the book-like story of Marathon.
