Buy? Likely. Retrovirus is a Six Degrees of Freedom (6DOF) FPS about a world within a person's computer, where a destructive worm has infected and corrupted the system. Your task as an agent of the anti-virus program is to of course, delete this worm. Emails scattered across the system, hints to the reasoning behind the worm attack.
6DOF essentially means freedom of moment, so you're constantly flying and have to deal with threats that can occur from any angle in 3D space. RV can't escape (and possibly doesn't want to) the comparison to Descent and Forsaken/Forsaken 64 - I think the developer refereneces Descent in forums.
Mecanics are based on weaponry and technology that use a limited, but regenerative resource called cycles that are displayed on your gun. You also have a scan function to highlight enemies, a charged scan to scan a wide area of enemies and to activate marks (bullet holes) made by your weapons. These marks vary depending on the weapon, such as a small explosion with the pistol-like Dual Strike, push back with the minigun style Thrash, or creation of gravity wells with the shotgun-like Interruptor, my personal favoritte. The use of cycles essentially means unlimited ammo, but requires you to manage shooting as you can easily run out if you shoot too much and you don't have any reload canisters. This is a problem with the larger hoard fights and some boss fights as there where times I felt I couldn't deal with the threat and I felt impossible with the Corrupted Driver boss battle (until I found a level exploit). You can also upgrade your "ship" and weaponry with bytes earned from killing enemies, destroying corruption and orange byte pickups which I think are called Memories.
I LOVE the high tech "Futuristicy" art style, though I'm not sure what I think about the combination of that mixed up with destroyed stone and concrete walls thanks to the Worm. I guess the idea is that the Worm is so destructive, that it's destroying the actual physical structure of the machine (though, the system is nothing like any computer I've any seen, it's obviously an interpretation)
I found the game mostly enjoyable and I enjoy the technology puns and references - computer geeks may get a laugh out of the dialogue's sense of humor. I did get more annoyed near the latter quarter of the game where I died alot due to a couple bosses and a couple hordes. It's a shame that this game wasn't advertised well, because hardly anybody knows about it and there's never anybody available for Co-op campaign or competitive multiplayer (except for certain Days when the developer hosts game sessions).
If you're somebody that liked Descent or Forsaken, or a computer geek that likes sci-fi FPS games, this game is definitely worth checking out - it provided me with at least 12+ hrs of gameplay (admittedly, more deaths than I'd like). I must warn you that the game may require a strong gaming system, as the frame rate can drop significantly - it has 12-15fps on my Intel HD laptop and drops like crazy when I accidentaly leave Folding@Home on (though, it's CPU intensive anyways, but many players mentioned performance problems - look at the community hub) Due to the lack of community, it's probably best to wait for a sale or bundle.
