## INGAME CONTROLS

**Fixed Controls**

| | |
| --- | --- |
| **Key(s)** | **Purpose** |
| `Enter` | Choose a menu option |
| `Escape` | Go back to the previous menu |
| `F9` | View in-game statistics (e.g. FPS) |
| `P` | Pause the game |
| `Alt + Enter` | Switch between full-screen and windowed mode |
| `1-5` | Switch weapon to Blaster, Toaster, Missile, Bouncer or TNT respectively. If the desired weapon is not available, try next. |

**Configurable Controls**

These are configurable via the "setup options" menu. Default settings:

| | |
| --- | --- |
| **Key(s)** | **Purpose** |
| `Left arrow` and `Right arrow` | Move left and right |
| `Space bar` | Jump/Swim upwards |
| `left Alt` | Shoot |
| `right Ctrl` | Change weapon |

**Important**\

Under Windows the Jump and Shoot keys are moved to the right to avoid opening the window context menu. That means `Space bar` ⇒ Shoot and `right Alt` ⇒ Jump/Swim upwards. Other platforms may have other defaults.

**Game Controllers**

Most game controllers and joysticks that SDL recognizes can be used.\
 However, not all axes or buttons may be available. Needs manual settings.
