What the developers have to say:

Why Early Access?

“Hello, my name is Spasman. I'm an amateur game developer who creates games by himself, outside of some occasional freelancer help. I'm here to tell you about the progress of my new project, TUNNEL DIVERS.

The foundation for TUNNEL DIVERS is pretty much done. However, I don't have a lot of opportunities in terms of testing, so I'd like to ask you, the public, to help test my game before I release it. My main goal in Early Access is to find any devastating problems with the multiplayer netcode. Hit registration, lag, connection issues, etc. I am fully ready and able to rewrite large parts of the code if it comes down to it, but heres to hoping I get lucky.

Once those wrinkles are straightened out, then I can start moving towards release with content updates for the multiplayer and releasing a full single player campaign.

I've mostly made small or multiplayer-focused games, so a full campaign is something I'll be new at. I am thinking of releasing the campaign bit by bit, and hearing feedback from the community so I can mold my level design sense and apply it to the final product. Story writing isn't a strong suit of mine either, so I'll probably take a minimalist approach with that.

Lastly, weapon/ship balance and gameplay. Hopefully a competitive community can take off and I can hear about what weapons or ships are too strong, or what maps are poorly designed. I'd also like to hear feedback on the core gameplay, like if its too "flat", boring or fast. I can then tweak (or completely redo) these mechanics to fit the community's needs.

Thank you for joining me on this journey. I hope you enjoy the game and we can work together to make it great.”

Approximately how long will this game be in Early Access?

“As a gamer myself, I can be the first to tell you that Early Access games aren't exactly in my favor. So while I'd love to escape EA hell as fast as possible, it would not be wise for me to be reckless with a release, considering I am only one guy without a dedicated QA team. I learned this the hard way with my last Steam game.

I usually burn my weekends working on this project, so if I keep at it, the game should ease into completion by summer of 2018, at the latest.”

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

“The full version will have a complete campaign, tons of ship patterns and afterburner effects, and hopefully a very populated Workshop community.

I would also like to include a handful of multiplayer maps to come with the game and a fully made campaign.

As for ships, I'm not sure what the final count will be. But more will be on the way, I can guarantee that much.”

What is the current state of the Early Access version?

“Like I mentioned earlier, the foundation for the game is mostly done. I think the core gameplay is pretty solid right now, and the game is ready to have content scaled onto it such as new ships and new weapons.

At face value, I think the game plays like a fully completed game. However there will be many bugs and problems to be rooted out before release, and as one person I can't find them all on my own, so I'm humbly asking the Steam community to help me ride this game into a more polished state.

The netcode is widely untested. You may experience latency problems, connection and hosting problems, and hiccups with the Tunnel Servers system. I'm also worried about hit registration problems, as client prediction and everything that goes into what makes hitreg good is probably the most complex part of coding an online game. I will be watching servers hosted by me and hosted by others very closely to see how well the hit registration is doing, and may perform various experiments to see which kind of methods would work best for the game and for Game Maker's network functions.

As with a lot of online games, you will need to portforward to truly host your own server. To circumvent this, anyone who owns the VIP DLC will be able to generate a server of their own on the cloud, however I highly recommend learning how to host a server from your own network as it will probably be much less laggy for yourself and others who may be in your region. I'm still bit of an amateur, so I'm hosting the cloud servers and any regular servers I may have up from my apartment and two virtual private servers.

The level editor is also very usable, and you should be able to make some fully functional levels and upload them to Workshop. The Workshop menu might need some work in the intuitive GUI department but its usable and if you don't like it, you have easy access to the Workshop pages themselves from in-game until I can improve on it.

Lastly, there is full controller support, however I've mostly designed with Mouse/KB controls my whole life. So the default controller bindings might be a bit wacky. However you can do just about anything with the game from a controller (except the level editor), from simply playing the game, to being able to name and host your own server.”

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

“TUNNEL DIVERS is a free to play game on a competitive level. If you wish to support the game, The VIP Access DLC will unlock extra features that shouldn't give a player a leg up on any freemium players. The VIP Access DLC will remain the same price throughout the game's lifetime.”

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

“I'm going to keep a close eye on the forums and my email for feedback. If you have suggestions or comments or bug reports, you can send me an email at spasman@spasmangames.com”

A Tunnel Divers gather is now starting!

The gather is starting! Please come join "[US] Spasman's Server" in the server list if you want to help playtest the multiplayer.

If it's somehow full (I don't think it will be), then just join one of the other servers and I'm sure others will follow. The point of this is to play with eachother, not just with me. I probably spectate most of the time anyhow.

I'm going to start doing this almost every weekend, so if you missed today don't feel bad. We have a discord server, so come join if you want to be up to date on gathers: https://discord.gg/XARR493

Thanks for your support!

Tunnel Divers Gather - This Sunday (2/11)

Hi, I'd like to make a gather for this sunday. If you don't know what that is, its when our small playerbase gets together to playtest the game.

I would like to schedule it Sunday, 12PM MST time. Google can convert time zones for you.

I'll post another announcement when I'm about to play.

About This Game

Welcome to your new line of work, pilot.

TUNNEL DIVERS is an online free to play action game featuring futuristic space fighters that are specialized in destroying hordes of robots in enclosed spaces. With plenty of ships and weapons, claustrophobia won't be the most dangerous thing in the tunnels.

TUNNEL DIVERS is free to play and has no pay-to-win attached. Play online with your friends and against other pilots without feeling disadvantaged because you didn't pay for any DLC. The only one who should be paying are the suits from TAC-CORP!

TUNNEL DIVERS is a lightning fast twin stick shooter, you need to keep your ship on the move while combating hordes of robots or enemy players. Only those with the best reflexes and aim can come out as the top pilot.

Play cooperatively with your friends in missions, run the flag in Capture the Flag or just slaughter your enemies in Dogfight mode. More game modes on the way.

Vaporize your enemies with powerful weaponry, from long range laser guns to destructive miniature nuclear bombs.

Completely customize how your ship of choice is loaded out with weapons and special modules that can give you an edge in a fight. Earn money by completing matches and unlock more and more equipment.

Play missions and competitive levels designed by pilots all around the world. With painless map sharing, you can join a server without worrying if you have the correct files on your computer or not, as the game can automatically pull level files from the Workshop or the server host itself. Using the Workshop is completely free, however you will need to own the TUNNEL EDITOR DLC to create or edit levels.

Enjoy the musical talent of Gergely Kovács, who composed a full soundtrack for the game. If you like the music, please consider buying the game's soundtrack from him, a link will be available in the game's main menu!
