Borderline getting started
Go stealth-first until it breaks. The prologue's two missions teach the new noise and prone systems — and you can finish both without ever getting spotted.
Borderline is a stealth sandbox, and the fastest way to enjoy it is to play it like one. Go quiet first, learn how the alarms work, and treat the loud option as something you spend — not something you default to. Both missions can be finished with a full ghost run; both can also be finished with the smoke alarm ringing, if that is your mood.
Before you launch
- Check your language. Borderline ships with 12 text languages including Simplified Chinese, Japanese, Korean and Russian; set the one you want in Steam's game properties if it does not default correctly.
- Controller or keyboard? Full controller support is listed, including DualShock and DualSense pads. Keyboard players: there is no public bindings sheet yet — remap in-game after launch rather than trusting trailer footage shot on the developer's own layout.
- Hardware floor is low. The minimum spec is a 2011-era i3/Phenom and a 512 MB graphics card; the recommended target is a Ryzen 3 3300X and an RX 460-class GPU at 144+ FPS on high settings. A 2 GB install, DirectX 9.
The first thirty minutes, as a checklist
- Watch a patrol before you touch it. The prologue is built around reading routes; enemies who have not seen or heard you are slow to react, and that window is the entire game. Details live in Stealth systems.
- Test prone early. You can now fire every weapon and use most gadgets lying down — rehearse it in a quiet room before you need it under pressure. See Movement & prone.
- Click a guard before you kill a guard. Close-quarters prompts offer KILL, CHOKE and PICKPOCKET — the non-lethal options are real tools, not set dressing. See Combat & gear.
- Finish a maneuver, don't half-finish it. Reloads commit once started. Plan the quiet action and the escape line before you touch the button.
- Get high. Vaulting and climbing now work on almost everything. The second floor and the fire escape are usually the stealth route.
Stealth-first, but never stealth-only
The store page frames the loop as a choice with teeth: use darkness, sound, distractions, gadgets and the environment to stay unseen — or abandon subtlety and fight, where "positioning, weapons, ammunition, and split-second decisions can mean the difference between walking away and bleeding out".
What that means in practice: the game is not scoring you on purity. A silent start that turns into a running firefight because someone walked around the corner is a legitimate session, and the new reaction system actually gives you the seconds you need to handle it — enemies that are calm react slowly, so mistakes are survivable if you keep your head.
Gunfights are also not a mystery: the loud path uses the same systems as the quiet path. Sound pulls guards toward a general area rather than your exact position, which means you can use your own gunfire to move the board.
What Borderline is teaching you
The prologue is explicitly a systems showcase for the full game: "deeper systemic stealth, more reactive enemies, expanded tactical options, extensive weapon customization, new equipment and gadgets". If a mechanic feels new here — the noise windows, prone combat, climbing routes — expect it to be load-bearing in Intravenous 3 in 2027.
