Start Playing Without Losing the Map

OpenFront can become confusing when you need to build, attack, move the camera, and react to another player at once. This quick guide gives you the practical controls first, so you can make decisions instead of searching menus during a fight.

Your basic loop is simple: look at the territory around you, choose whether to build or attack, and keep your view centered on the situation that matters. The current shortcuts reference applies to v33.5, verified on August 16, 2026, so use it as the main control reference.

Before you commit to a fight, remember that attacks work through reachable borders. The older community how-to-play page also notes that a normal left-click attack requires sharing a border with the selected player. Water attacks use transports instead.

| Goal | Current default control | What it does | |---|---:|---| | Attack by land | Left-click | Attack an enemy or unowned border | | Send a transport | Left-click across water | Send a transport across water | | Open the build menu | Ctrl + left-click | Open the Build menu at that location | | Open radial/build menu | Right-click | Open the radial or build menu in the default scheme | | Cancel a preview | Esc | Cancel a build preview or close a menu | | Place an armed unit | Enter | Build the selected unit under the cursor |

The exact mouse layout can be changed in Settings through “Left click opens menu.” If you use that option, do not assume the default left-click behavior still applies; check your own setting before a match begins.

A useful first habit is to keep your actions intentional. Do not leave a build preview armed while trying to attack, and use Esc when you want to return to normal map interaction. That prevents accidental placement and makes the next click easier to understand.

Learn the Build and Unit Keys

The number keys are the fastest way to reach common structures and nuclear units. Tap a number once to arm the listed option, then left-click on valid land to place a building or use the selected weapon.

For existing structure upgrades and Atom Bombs, pressing the same build key again toggles between x1 and x5. New structures, Hydrogen Bombs, and MIRVs remain x1. The radial menu provides more batch choices for structures and Atom Bombs, including x1, x5, x10, and xMax.

| Key | Action | Important behavior | |---|---|---| | 1 | Build City | Arms one City build | | 2 | Build Factory | Arms one Factory build | | 3 | Build Port | Arms one Port build | | 4 | Build Defense Post | Arms one Defense Post build | | 5 | Build Missile Silo | Arms one Missile Silo build | | 6 | Build SAM Launcher | Arms one SAM Launcher build | | 7 | Build Warship | Arms one Warship build | | 8 | Atom Bomb | Press again to toggle an x5 loaded-tube batch | | 9 | Hydrogen Bomb | Stays armed for repeat fire | | 0 | MIRV | Arms one MIRV |

If you press 8 once, you prepare one Atom Bomb. Pressing 8 again changes the existing Atom Bomb action to an x5 batch, then you left-click to use it. Gold and loaded Silo tubes limit xMax batches.

The shortcuts reference says bombs from the same Silo leave one tick apart. Separate ready Silos can fire together. That distinction matters when you are practicing launch timing: repeated launches from one source are not identical to simultaneous launches from separate ready sources.

Use U to flip the launch arc of an armed nuke up or down. Use Enter to build the armed unit beneath the cursor, or Esc to cancel it. These keys are especially helpful when a crowded map makes precise clicking difficult.

The build keys do not decide whether a location is strategically good. They only reduce the time between deciding and acting. For example, a Port supports water access, while a Defense Post is a separate build option; choose them based on your position rather than treating every key as an automatic opening sequence.

Control Combat, Ships, and the Camera

Combat controls let you change how you attack without repeatedly opening menus. G launches a ground attack toward a target, and B launches a boat attack toward a target. T decreases the attack ratio, while Y increases it.

The older attacking guide describes the bottom-left sliders as controlling the troop-to-worker ratio and the share of troops used per attack. Treat those descriptions carefully because that page says it was last updated for v23.0 and warns that its accuracy may be out of date. The current v33.5 shortcut list is the better source for default key inputs.

| Situation | Key or input | Result | |---|---:|---| | Ground attack | G | Launch a ground attack toward the target | | Naval attack | B | Launch a boat attack toward the target | | Lower attack ratio | T | Decrease the attack ratio | | Raise attack ratio | Y | Increase the attack ratio | | Retaliate | Shift + R | Retaliate against the player who last attacked you | | Select all warships | F | Select all of your warships | | Select several warships | Shift + drag | Box-select multiple warships | | Cancel ship selection | Right-click | Cancel an active Warship or boat selection |

Warship selection is worth learning early. Press F when you need all of your Warships, or hold Shift and drag to select a group. The v33.5 reference notes that the Shift-drag warship selection remains a fixed default in that release.

For navigation, use the mouse wheel to zoom and middle-drag to pan. You can also use Q to zoom out, E to zoom in, and W, A, S, and D to pan. The + and - keys are fallback zoom controls.

Space switches to an alternate view between terrain and countries. M toggles the coordinate-grid overlay, and C centers the camera on your nation. These are not cosmetic conveniences: when the board becomes busy, a clear camera view helps you avoid clicking the wrong coast, border, or target.

Use Alt + R to reset graphics if you need to restore the visual presentation. In single-player, P pauses or resumes, while comma and period lower or raise game speed.

Make Safer Early Decisions

A reliable start is less about memorizing a perfect build order and more about recognizing the immediate decision in front of you. OpenFront’s guide directory emphasizes several recurring choices: whether to expand, where teammates should spawn, whether to attack across water, and when to protect a lead.

Start with these priorities:

  • Learn where your land borders end and where water begins.
  • Build only after identifying the purpose of the structure.
  • Use land attacks for reachable enemy or unowned borders.
  • Use a transport when crossing water.
  • Keep the camera close enough to confirm the target before committing.
  • Cancel an armed build with Esc if the board changes.

The guide directory highlights that transport landings need a reachable coast, capped waves, a Warship screen, and a beachhead. It also recommends canceling a failing operation before it empties your home front. That is a useful warning for newer players: crossing water can create a distant commitment while your original territory still needs protection.

The same directory points players toward tall-versus-wide decisions. Before expanding from a compact core into another foothold, consider liquidity, access, need, and deadline. In plain terms, do not take more land just because it is available if the new territory creates a weak route or pulls attention away from a more urgent defense.

Defense Posts are another decision that depends on placement rather than mere availability. The directory describes a 30-tile defense zone and a 50-tick build, and frames the choice as whether a second line is better than stacking one tile. Use that as a planning question: consider where protection will matter before you begin the build.

| Decision | Questions to ask | Relevant source guidance | |---|---|---| | Expand or stay compact | Do you have liquidity, access, need, and time? | Test tall versus wide before creating a second foothold | | Land across water | Can you reach a coast and preserve your home front? | Use capped waves, a Warship screen, and a beachhead | | Defend a coast | Is a sea route becoming unsafe or disconnected? | Screen transports and know when to fall back to land | | Add a Defense Post | Does one line cover the important area? | Consider the 30-tile zone and 50-tick build | | Coordinate with allies | Are teammates blocking shared routes? | Reserve City, Factory, Port, and rail corridors |

Diplomacy has quick defaults too. Hover a player and press K to request an alliance, or L to break one. The older community page says its radial menu can show player information, emoji, alliance, marking, donation, and betrayal options. Because that source is older, use it as context rather than as a current interface guarantee.

When you need a simple tactical reset, stop trying to do everything at once. Center the camera with C, press Esc to clear any active preview, identify the border or coast that matters, then choose one action. That rhythm is often more valuable than fast but unfocused clicking.
