Boundary is a first-person tactical arena shooter that pits players in two-team low-gravity space engagements, with a somewhat similar premise to Rainbow Six Siege split character teams and round-based matches. A demo for the game was available in February 2023, and the game was fully released on April 13th, 2023.
Boundary stands out from the FPS genre as it is the first full-fledged title set in space. The players take control of several combat-ready astronauts with their dedicated strike packages, akin to the operators/heroes with unique abilities in different games. Players are divided into to two teams, the Solar System Defences and the Vacuum Exiles. The real-world firearms and custom "Generic Soldier Weapon" series are all purpose-tailored for space combat, with white anti-radiation paintjobs and typically featuring heavy-profile barrels, heat sinks, and modified triggerguards or 'D'-shaped cutlass guards on pistol grips.
Boundary functions as a six-axis shooter, with the astronaut player characters having Manned Maneuvering Unit (MMU)-type thruster systems incorporated into their spacesuits. Player characters can walk and crouch on satellite surfaces when in an upright position upon them. The effects of recoil for many of the small arms are generally canceled out by the MMUs, though the machine guns and high-caliber marksman weapons will push the player character back if fired while floating stationary, and will slow down players down if they are moving forward against the projectile direction.
The following weapons appear in the video game Boundary:
A modified, white-painted Stechkin machine pistol is one of the sidearms and comes standard for Orlan. It is presumably made from the APB variant with the compensator mounted on the APB's extended barrel. There is no suppressor modification available in game, though the wire stock is. It fires in semi-auto by default, with the full auto option only available as an unlock.
AK pattern carbine
An AKM pattern carbine is available as the "TK47" - it comes with a short AIMR-style barrel by default, but a standard length AKM barrel is an available unlock. This is a starting weapon for the cosmonaut Orlan. The AK is heavily customized for use in space - it has a coat of reflective white space paint, a fictional combination heat sink/Picatinny rail handguard, a custom wire stock. The triggerguard is also removed, and a custom pistol grip featuring a knuckle cutlass is installed for use with spacesuit gloves.
An SVD heavily modified for exoatmospheric use is one of the marskman/sniper weapons available in the game. It has a standard Dragunov receiver with a ribbed topcover and Zenitco-style RIS scope mount, and a shortened carbine barrel with a combination gas block/front sight akin to the SVDM.
Type 53 Mosin carbine
A heavily customized Chinese Type 53 Mosin Nagant carbine appears as the "M53" and is exclusive to the Marksman role.
A heavily modified, white-painted RPK is one of two machine guns available to the Astronaut Fortress. It has a tubular heat sink assembly over the entire barrel assembly and handguard, and white visor-style stock attached. It also has a railed top cover with a rear aperture sight, unlike the AIMR AK carbine.
"Generic Soldier Weapon" series
The primary collection of firearms available in the Boundary are built around a fictitious "Generic Soldier Weapon" platform, which mainly consists of an IWI X95 style cutlass trigger pack and various sci-fi receiver bits. The "GSW-AR, GSW-PCC," and the "GSW-SMG" are listed here; see the talk page for the other variants that have fictional operating systems that don't match current real-world firearms. The entire family is the following:
The "GSW-AR", with AR standing for Assault Rifle, is put together in a bullpup package with some resemblance to an entire IWI X95 rifle.
The "GSW-PCC" is a pistol-caliber counterpart to the -AR, and swaps the top handguard and full length Picatinny rail for a railed carry handle vaguely like that of the ShAK-12.
The "GSW-SMG" variant is another SMG, this time in a package fairly similar to a KRISS Vector.
