HITMAN Update 3.290 Changes Stealth, but Guards Apparently Have X-Ray Vision

HITMAN World of Assassination's October 29 Update 3.290 introduces some genuinely interesting stealth changes. Agent 47 can now conceal illegal weapons using his own body or nearby objects, hide targets inside containers, and attack characters already stashed away. Unfortunately, players are already reporting that the new weapon-concealment system doesn't always work as advertised. Apparently, even walls are no match for the observational brilliance of private security.

Wondering whether HITMAN is still worth playing beyond the latest patch? Our HITMAN World of Assassination review explores the disguises, assassination opportunities and criminal ingenuity that make Agent 47's profession so disturbingly entertaining.
Apparently, Guards Can See Through Walls Now
According to IO Interactive's official patch notes, 47 can now conceal an illegal item by physically obstructing an NPC's view. Turn your body to hide a pistol, position yourself behind a pillar, or use a wall to conceal whatever unpleasant business you're carrying. It's a wonderful idea. Instead of automatically detecting every exposed weapon, guards are supposed to consider whether they can actually see the damn thing.
Unfortunately, some guards appear to have developed X-ray vision. In the HITMAN Forum's October 29 patch discussion, user HitmanDoctor reported that 47 sometimes failed to perform the concealment animation. More concerningly, a guard allegedly detected a drawn weapon behind a wall despite only 47's head being visible. Another player, jan342, described a similar incident involving a pistol concealed behind a statue, while chuckmcgillgaming also reported getting caught attempting the technique.
Imagine being a professional assassin capable of infiltrating practically any building on Earth, only to be exposed by a security guard who can apparently identify a handgun through reinforced concrete. Forget assassinations. Hire the bastard. He could replace every airport security scanner in Europe, and Heathrow might finally process a passenger before their passport expires.
These are individual player reports rather than proof of a universal bug, but they raise legitimate questions about the mechanic's reliability. For now, relying on body positioning to protect an important Silent Assassin run seems unnecessarily adventurous.

Hiding a Target No Longer Makes Them Untouchable
The second major change concerns containers. Characters hidden inside them are no longer automatically protected from subsequent attacks. Bullets can strike concealed characters if they intersect their actual body hitboxes, while explosions can also affect occupants. Designated targets can now be stashed away, too.
That creates an intriguing possibility: incapacitate your target, hide them in a wardrobe and potentially finish the assassination later with a firearm or explosive. It's an elaborate approach to murder, admittedly, but Agent 47 has never struck anyone as a man who believes in keeping things simple.
Community members have already discussed possible applications involving Contracts mode, Freelancer suspects and assassination challenges. However, those discussions don't establish which specific strategies work reliably. Shooting a container doesn't guarantee hitting its occupant, and the consequences for Silent Assassin scoring remain unverified. Players who previously relied on containers to protect unconscious NPCs from explosions may also need to reconsider their approach.
Grenades Get Smarter, Bananas Get Nastier
Two smaller adjustments could influence established tactics. NPCs should now recognise live grenades, warn others and attempt to escape instead of standing around contemplating their imminent transformation into wallpaper. Meanwhile, thrown bananas now split open on impact, activating their slipping effect without requiring manual placement.
There's something magnificently HITMAN about an update that improves human survival instincts around explosives while simultaneously making airborne fruit a more effective instrument of violence.
Both changes create potential opportunities for distractions and improvised takedowns, although their usefulness in specific mission routes still needs confirmation.

What Actually Changes for Stealth Players?
Update 3.290 introduces meaningful new possibilities, particularly for container-based assassinations and environmental weapon concealment. However, their practical reliability hasn't been established across missions, and early community reports suggest that weapon detection can behave inconsistently.
Experiment before incorporating these mechanics into established Silent Assassin routes. Agent 47 has survived international conspiracies, heavily guarded compounds and some of the world's most dangerous criminals. Having his disguise blown because a security guard spotted a pistol through a wall would be a particularly humiliating way to ruin his afternoon.
HITMAN Update 3.290 FAQ
Can guards still detect illegal weapons behind walls?
Yes. Although Update 3.290 introduces weapon concealment through body positioning and environmental cover, several players have reported guards detecting weapons that appeared to be obstructed. The mechanic's reliability remains questionable.
Can you kill targets hidden inside containers?
Yes. Bullets and explosives can now damage characters inside containers, including mission targets. However, bullets must hit the concealed character's actual hitbox, so shooting randomly at a container won't necessarily work.
Do the new stealth mechanics affect Silent Assassin ratings?
Potentially, but their effects on specific missions and challenges haven't been reliably established. Players should test new assassination techniques before relying on them during Silent Assassin runs.
What changed with bananas and grenades?
Thrown bananas now activate their slipping effect upon impact. NPCs also respond more appropriately to live grenades by recognising the danger, warning others and attempting to escape.
