No special access warning is needed. Online functions can be affected by platform subscriptions, service availability, account requirements, or an unavailable matchmaking service.
Fast answer
The answer before the background
Yes, the game can be played offline for its solo content, provided the installed copy has already been launched and configured for offline use. Online co-op and versus modes are available on Steam, PlayStation 4, and Xbox platforms, with two players supported. The Switch edition officially advertises local two-player modes but does not list online multiplayer. There is no verified native browser version. You may be able to stream the game through a cloud-gaming service in a browser, but that is a separate service-dependent option, not a built-in web version.
At a glance
Which modes work online and offline?
The safest way to think about access is to separate the main game from network features. The campaign, challenge missions, map-based play, and other solo content are designed to run locally once the game is installed. Multiplayer is an additional layer that needs the relevant platform network and, on consoles, any required online subscription.
The official game manual describes both competitive play and cooperative play. Its cooperative modes include Coordinated Defense, where two players share one defensive base, and Doubles. Its versus mode is DG Fighter, where each player sends stronger enemies toward the other player by defeating aliens on their own map.
- Offline solo play: supported after installation and offline preparation.
- Online co-op: verified on Steam, PlayStation 4, and Xbox listings for two players.
- Online versus: listed for the Steam version and described in the official game manual.
- Local multiplayer: available on supported releases, but the exact mode depends on the platform.
- LAN play: not clearly verified in the current official listings, so do not assume it is supported.
| Access method | What to expect | Confidence |
|---|---|---|
| Offline | Solo campaign and other local content should work after setup. | Verified platform behavior; follow offline preparation steps. |
| Online co-op | Two-player cooperative play on Steam, PlayStation 4, and Xbox. | Verified by current store listings. |
| Online versus | Competitive multiplayer is listed on Steam and described in the manual. | Verified, but real-world matchmaking activity may vary. |
| Browser | No native web edition verified. Cloud streaming may work through some services. | Service-dependent and subject to change. |
A game can remain playable offline even when its online services, matchmaking, leaderboards, or cloud features are unavailable. Losing internet access does not automatically remove the installed solo campaign.
PC setup
How to prepare an offline copy on Steam
For Steam, install the game and launch it once while connected. Confirm that the download is complete, allow any required updates or first-run installation steps to finish, and check that the game reaches its main menu. Then use Steam's Offline Mode before disconnecting. Steam's support instructions state that most games need one connected launch before they can be started offline.
Offline Mode disables Steam functions that require a network connection. That means online multiplayer, cloud synchronization, community features, and other network-dependent services will not be available. Local saves can still be used, but you should close Steam normally rather than forcing it to quit so that local data is written correctly.
- Install the game completely while connected.
- Start it once and wait for any setup or updates to finish.
- Exit the game normally.
- Choose Steam's option to go offline while the client is still connected.
- Test the game before travelling or disconnecting for a long period.
- Reconnect occasionally if you need updates, cloud synchronization, or online multiplayer.
| PC version detail | Current guidance |
|---|---|
| Windows on Steam | The most straightforward supported PC route for current troubleshooting. |
| Mac and Linux | Hidden Path's launcher says official support ended in 2016. Existing installations may behave differently, so treat them as unsupported rather than guaranteed. |
| Steam Workshop and cloud features | Useful online services, but unavailable or limited while offline. |
| First launch | Do it online before relying on offline access. |
If offline access is your priority, test the exact machine and installation before leaving an internet connection. This is more reliable than assuming that an old installation will start after a long period without updates.
Console comparison
PlayStation, Xbox, and Switch differences
The PlayStation Store lists the PS4 release as supporting up to two online players and says PlayStation Plus is required for online play. It also marks online play as optional, so the single-player experience does not depend on a subscription.
The Xbox store lists Xbox One and Xbox Series X|S compatibility, online co-op for two players, online multiplayer for two players, and local co-op or local multiplayer for two. The platform listing is the clearest current confirmation for Xbox access.
Nintendo's official Switch listing advertises a two-player Story Mode and two-player Coordinated Defense Mode locally. It lists one-system support for one to two players, but does not advertise online multiplayer. Do not purchase the Switch version expecting internet co-op unless the exact Nintendo store page for your region explicitly adds that feature.
- PlayStation 4: online play for two; PlayStation Plus required for online play.
- Xbox One and Xbox Series X|S: online and local two-player features are listed.
- Nintendo Switch: local two-player Story Mode and Coordinated Defense are advertised; online multiplayer is not listed.
- PlayStation 5: the PS4 version may run through backward compatibility, but Sony warns that some PS4 features can be absent.
| Platform | Online multiplayer | Local multiplayer | Best use case |
|---|---|---|---|
| Steam | Yes, including co-op and versus. | Yes, according to the store feature list. | Flexible PC play and online access. |
| PlayStation 4 | Yes, up to two; PS Plus required. | Two-player support is listed. | Console online co-op. |
| Xbox One / Series | Yes, two-player co-op and multiplayer. | Yes, two players. | Xbox users wanting both local and online modes. |
| Nintendo Switch | Not advertised by the official listing. | Yes, one system for one to two players. | Portable or same-room co-op. |
Store feature labels show intended support, not a guarantee that public matchmaking is busy or that every old service is operating perfectly. If an online search fails, test a direct friend invite and check the platform's network status before assuming the game is offline-only.
Browser access
Can you play it in a web browser?
There is no verified native browser edition in the official game listings. You cannot normally open a webpage and run the installed game as HTML or a browser download. The browser option discussed by cloud-gaming references is cloud streaming: the game runs on a remote computer or service, and video is sent to your browser.
This approach may require owning the game, using a supported storefront, installing an app instead of a browser, or paying for a cloud-computing subscription. Catalogs and regional support can change, so browser availability should be checked at the provider before subscribing. Cloud streaming also needs a stable connection, and multiplayer quality depends on both the streaming service and the game's own network features.
- Native browser game: not verified.
- Cloud-streamed browser play: possible through some providers, but not guaranteed.
- Offline browser play: not expected, because streaming requires an active connection.
- Best low-risk option: install the game locally on a supported platform if you need reliable offline play.
| Question | Answer |
|---|---|
| Is there a web version? | No official native browser version was verified. |
| Can a browser launch it through streaming? | Possibly, depending on the current cloud provider and region. |
| Does browser streaming remove the purchase requirement? | Usually not; many services require you to own the game. |
| Can browser play work offline? | No. Streaming requires an active network connection. |
Treat browser access as a convenience option rather than a separate release. For dependable solo play, local installation is the better choice; for online co-op, use the platform with a current official multiplayer listing.
Troubleshooting
What to check when multiplayer does not work
First confirm that both players are using the same supported platform family and that the game is fully updated. On consoles, check the required subscription and make sure both accounts can use online multiplayer. On Steam, leave Offline Mode, restart the client, and allow the game to connect through the firewall.
If matchmaking is empty, try a private invitation or direct friend join. The official FAQ describes inviting a friend from the multiplayer menu. If invitations fail, check platform service status, router restrictions, and firewall rules. Community reports can be useful for identifying current problems, but they should not override the platform store's documented feature list.
- Update the game and platform client.
- Confirm that both players have the correct online subscription where required.
- Use a friend invite rather than relying only on public matchmaking.
- Check firewall, router, and platform network status.
- Test solo play to separate an installation problem from an online-service problem.
- If using Mac or Linux, remember that official support ended in 2016.
The multiplayer modes and platform capabilities above are documented by official store pages or the official manual. The troubleshooting steps are practical recommendations. Current player population, matchmaking reliability, and cloud-service availability are not guaranteed.
FAQ
Common questions
Can the game be played without an internet connection?
Yes. The solo campaign and local content can be played offline after the installation has been launched and prepared while connected. Steam specifically recommends testing the game before switching to Offline Mode.
Does it support two-player online co-op?
Yes on Steam, PlayStation 4, and Xbox listings. The supported online player count is two. The Switch listing advertises local two-player modes but does not list online multiplayer.
Can two people play together on one console?
Yes on supported console releases, but the exact features differ. Xbox and PlayStation list two-player local or multiplayer support, while Nintendo officially advertises local two-player Story Mode and Coordinated Defense Mode.
Is there a browser version?
No native browser version was verified. Cloud streaming may let you play through a browser when a provider supports the game, but that requires an active connection and may require ownership of the game.
Why can I play solo but not join a friend?
Solo play does not depend on matchmaking or platform network services. Check updates, subscriptions, account permissions, firewall settings, platform status, and whether both players are using compatible versions. A direct friend invite is worth trying before public matchmaking.
