Ranked in these QuestionsQuestion Ranking
Pros
Pro Gesture controls work well
RoboRaid uses simple gesture controls for firing at the robots and these controls work well. The player uses air-tap gestures to fire a laser-like weapon while aiming at your opponents simply by looking at them. Incoming bullets, lasers and explosions can also be physically dodged.
Pro Well detailed enemies and visual effects
The image quality of the enemy models and the virtual destruction that appears on the walls is detailed and looks immersive because it blends well with the real world.
Pro Well implemented spatial sound
The spatial sound of the HoloLens is well implemented in RoboRaid, as you can hear enemies that appear behind you before you get any chance to spot them.
Pro Both enemies and player can interact with the environment
As with every HoloLens game, enemies can interact with the environment. RoboRaid makes good use of this feature, as enemies will have no line of sight if they're behind an object and robots show up from 'destroyed' walls in your environment. However, not only the enemy can interact with the environment as the player can use its own surroundings to its own advantage. The player can duck behind an object to hide from the robots or can use an obstacle as protection against enemy weaponry.
Pro Strong emphasis on audio enchances immersion
Fragments places a strong emphasis on audio, as it uses spatial audio to 'locate' a sound and a corresponding crime scene. Spatial audio is implemented well and further enhances the mixed reality experience.
Pro Adaptive character behaviour allows for unique gameplay situations
The characters of Fragments adapt to the environment and the player. For example, when playing inside a room with furniture, the life-sized holographic characters could be sitting on a sofa or a chair instead of a generic position.
The game also keeps track of the player's position, allowing gameplay elements such as characters sneaking up from behind.
Pro Allows the player to interact with the environment
The HoloLens completely scans your environment and allows the game to interact with it. A crime scene is displayed in your own room and the game allows to player to interact with it. Some elements will even be hidden underneath elements in the real world, such as your furniture.
Pro Adapts to both small and large spaces
Whether you're playing Fragments in a small room or a larger environment, the game will always display the most important aspects of a crime size according to room size.
Cons
Con Some scanning bugs deteriorate immersion
Some bugs might occur when scanning your environment for use in RoboRaid. Enemies might not pick up some elements such as pillar structures for example, or doesn't use walls as an 'entry point' for the invading robots.
Con Limited field of view has a noticeable effect
The HoloLens has a rather limited field of view of 120° (for comparison, the natural field of view of your eyes is 180°), which is a noticeable difference and can affect the mixed reality immersion of RoboRaid.
Con Some interaction glitches can deteriorate immersion
Some interaction glitches can be seen in current gameplay videos, specifically when a holographic character is 'stuck' between a real life object.
Con Image quality isn't up to par with screenshots
The image quality seen in gameplay videos is quite unsharp and toneless, with noticeable aliasing. Although Fragments is in very early stages of development and HoloLens hasn't been released yet, screenshots are somewhat unrepresentative of the current state of the game.
