Opocalypse
A downloadable game for Linux

Practice your orienteering skills with this simple but hopefully realistic simulator, based on automatically-generated maps (thanks to Lantmäteriet, Karttapullautin and OpenMapper).
This release includes 7 terrains, inspired by real-world data from national parks, nature reserves and other difficult-to-access areas in Sweden.


Movement
WASD: move forward, left, back, right
Q: hold down to move faster
E: jump
F: free look
Esc/Tab: pause
Map handling
Space: show map and compass
Mouse wheel: map zoom in/out
Mouse L/R buttons: rotate map
C: center map pivot near current location (+/- 150 m)
Terrain and map data
Height and vegetation data from Lantmäteriet (Swedish mapping, cadastral and land registration authority). Automated maps generated with Karttapullautin. Details like lakes, marshes, boulders, depressions are imagined and added with OpenMapper. Green/dense forest has not been implemented (yet), nor have any man-made features (probably never will). Courses set with OpenMapper. Simulator implemented using Unreal Engine 5.6.1 (Epic Games Inc.).
