Game Overview
A government-approved surveillance machine turns everyday digital life into your crime scene, and that unsettling premise gives Mainlining its bite. This is a darkly comic point-and-click investigation set entirely inside the desktop of a newly recruited MI7 agent, operating under the invasive BLU Pill Act. Messages, social profiles, browser trails, mobile data, and cracked passwords become the clues that lead from petty online offences to larger criminal networks. Its tone balances cynical British humour with a genuine concern for who deserves access to everyone’s private information.
Cases unfold through a convincing fake operating system packed with files, apps, databases, and communication tools. You search names and IP addresses, inspect metadata, retrieve deleted evidence, break into devices, follow digital conversations, and assemble enough proof to secure a conviction. Each investigation demands judgment as well as technical curiosity: arrest a suspect too early and valuable connections can vanish, but wait too long and the target may catch on and disappear. The challenge comes less from action-game reflexes than from reading evidence carefully, making logical links, and knowing which loose thread deserves another pull.
Mainlining stands apart by making its interface the entire world, turning familiar computer habits into detective work rather than using a conventional adventure-game map. Its cases encourage methodical players to revisit evidence and chase broader conspiracies, while the large pool of potential suspects gives the game a sense of an active criminal underground. The pixel-art presentation keeps the mood approachable, but the writing regularly returns to uncomfortable questions about surveillance, privacy, and institutional power. Fans of Orwell, Her Story, and classic investigative adventures will find plenty to enjoy, while newcomers can handle its accessible mechanics as long as they are willing to think like a patient digital detective.

Check that extraction completed and your PC meets the system requirements, including Version 9.0c. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
