This is a fun single player FPS co-op game that uses replays of up to 3 of your ghosts simultaneously to join you in a timed arena match and It brings a new intense experience.
Watching my ghosts come to life, move around, load up, test their equipment, and get to action was so much fun. I got to learn more about how I play from another perspective.
The point of the game is actually simple. You run around FPS style, shooting cubes and cube monsters that move in a set pattern and you have to destroy them all within a certain time limit before the round ends to achieve the full 100% completion. But this is where you can really enjoy the game because you can create a tactic and then switch it up on the following arena round leaving your ghost to do what you prepared it for like flanking one way while you go the other to shoot down cubes and cube monsters to try to achieve higher completion points. And if one tactic doesn't work then you can think of many different ones to use and have your ghosts perform them while you try different ones.
There are a lot of Steam achievements to earn and even some achievements that have you find intentional arena escape glitches and some cool features like being able record and upload your replay ghosts for others to download and play with them or you can download theirs as well.
The controls are very smooth and the game supports Keyboard & Mouse, XBOX 360 controller as well as the Oculus Rift VR headset. This game shouldn't have a problem running on older systems. I even tested it out on a gaming notebook running a GTX260m with a Dual Core 2.93GHz Intel processor and 1920x1200 resolution with all settings maxed except for AA and got a fluid 60 fps throughout the game. And the cool thing about the options in the game is that you can access and configure them right from your point of view in the main area by walking up to them.
This is an awesome game and once you get your hands on it you will have a lot of fun and try your hardest to get those 100% completion points. :D The only downside I found was reaching the end and wishing there was more. :(
