Evaluation
Acid Spy launched on June 8, 2018 as a complete first-person stealth action game. Following launch, the developer (Spin Slash) released a handful of feature patches — adding a checkpoint system, sonar scan ability, difficulty options, and quality-of-life improvements — across 2018 and 2022. The most recent update, on May 9, 2023, added Steam achievements. There have been no developer communications since that date, now over three years ago. No DLC has ever been listed for the game, no roadmaps or future content have been announced, and the store description contains no language suggesting ongoing or planned additions. The game appears to have shipped as a finished product and received polish updates over the years, with the achievement addition in May 2023 representing the final round of post-launch work.

About this game
Acid Spy is a first person stealth action game set in a cyberpunk universe. Infiltrate heavily guarded bases and take down your enemies with skill and finesse. Master the art of quick, deadly stealth to become the acid spy.
Expect lethal opposition from cyber soldiers armed with laser rifles. Equipped with a silenced pistol and combat knife the odds may seem stacked against you, but in the right hands a silent attack is more dangerous than any rifle.
Combat arenas are designed around player freedom. Study your enemies and attack where they least expect it. Remain unseen or prepare to be hunted down.
Parkour and mastering the movement mechanics of wall jumping and crouch sliding is essential to overcoming obstacles and defeating your enemies.
Stealth is usually the best course of action. This doesn’t mean you have to go slow. A skilled assassin moves quickly and strikes with deadly precision.
Completing the retro futuristic theme is a melodic synthwave soundtrack from Wolf and Raven.
