Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We’re a small team, and this is the most ambitious project we’ve built so far. The core game is in place, but we know it can improve with real player feedback.

Early Access gives us the chance to test the game with a wider audience, see what works, what doesn’t, and adjust things based on how people actually play.

We’d rather involve players now than guess everything ourselves and get it wrong later.”

Approximately how long will this game be in Early Access?

“We’re aiming for around 2 to 4 months in Early Access. This may change depending on player feedback and how development progresses.”

How is the full version planned to differ from the Early Access version?

“The full version will include more missions, additional weapons, and further gameplay improvements and features.

Coop, PvP, and the level editor will be fully accessible and expanded in the final release.”

What is the current state of the Early Access version?

“The current Early Access version allows players to fully play through multiple campaign missions. Checkpoints are implemented, enabling players to continue their progress within missions.

The core sandbox experience is already in place, including progression systems, weapon customization, and unlockable content. Players can freely engage with missions, explore the environment, and progress through the game as intended.

Coop, PvP, and the mission editor are not available at the start of Early Access and will be added step by step during development.

Some systems are still being fine-tuned, and minor issues may occur, particularly within mission scripting. These will be improved and expanded throughout Early Access.”

Will the game be priced differently during and after Early Access?

“The price will be increased over the course of the Early Access period.”

How are you planning on involving the Community in your development process?

“We read and consider all feedback, whether it comes from Steam, Social Media, or our official Discord.

We plan to stay close to the community throughout development and use that feedback to guide improvements and future updates for Beyond Enemy Lines – Vietnam.”

About This Game

Stranded behind enemy lines in Vietnam, you are cut off from command with no clear way out.

What started as a routine mission turns into a fight for survival deep in hostile territory.

Move through jungles, villages, and military outposts, choosing how you approach each situation. Stay quiet, set up ambushes, or go in loud when things escalate.

The battlefield reacts to your actions, and missions shift between open areas and more directed encounters. Play the full campaign solo or in 2-player coop and fight your way back - one step at a time.

Every encounter can be handled differently. Stay quiet and eliminate targets up close, fight through enemies with rifles, or use heavy weapons when things get out of control. At longer distances, precision matters just as much.

Fights shift fast, and reacting at the right moment can decide whether you push forward or get overwhelmed.

Earn new attachments through side objectives or by actively using your weapons. Each weapon progresses individually, unlocking new options over time.

Attachments offer both benefits and drawbacks, giving you control over how your weapon performs in different situations.

Use land vehicles, helicopters, and boats to move through the battlefield and support your mission. Reposition quickly, outmaneuver enemies, or bring mounted firepower into the fight when needed.

Vehicles are based on authentic military equipment used during the Vietnam War.

Earn experience, climb the ranks, and track your performance with detailed statistics. Every weapon features its own progression system and stat tracking, allowing you to refine your playstyle and optimize your loadout.

Unlock attachments, expand your arsenal, and showcase your progress in multiplayer. Whether you play solo, in coop, or in PvP, all modes contribute equally to your progression.
