Attention, this game is no longer updated, but have grater successor Dieselpunk Wars, that is currently being developed. It's allow to build land, sea, sub-sea, air vehicles in diselpunk settings and fight witch other creations. Have advanced water physics, air/water resistance, guns ballistic, damage mechanic with armor penetration, fire spread, flooding, explosion blast, cutting vehicle in half and many more.
Each construction is based on nodes, node can be wheel, wing, engine, balloon, propeller, tank etc.
Nodes can be connected by edges, moved, rotated, added and removed.
Vehicle can be divided to many segments by axes, axe can have rotation limit and can be individual steering
Game support air and water drag, wings can direct aerodynamic force to chosen direction. Nodes in water have own displacement, it can be changed in tank node so build submarine is possible.
Parameters of each elements can be changing in inspector, also it allows to rebind steering keys.

Hi, from version 0.5.0 I change editor to completely new one, this is faster, simpler, more stable and easier to use. But basic operation work different so manual can be useful.
After start new game new basic vehicle can be spawn by key C or New button, to enter to vehicle look at it seat (cockpit), seat cant be total occlude by other element and press F or Get In button.
First of all adding new modules. Select any green cube (node), on bottom is panel with available parts, click on chosen module, next drag one of red capsule to one of three axis, after move new module will be created.
To remove module, or any object press [Q] or Remove button on right.
To easy create new plate select edge (red cube) press [E] or Copy button and drag in any direction. In this way can be also created new module (with same setting), new edges by coping nodes and new cubes by coping plates (blue cube).
New plates (quad and tingles) can be also add by selecting three or four green nodes, multi-selecting can be do by holding [Shift] key and select 3 or 4 green cubes, next press  or Create button.
New edge can be add by same way by selecting 2 nodes.
Completely new is option to rotate any plates around one of it edge. To activate it select face, set on checkbox Can be Rotate, chose edge and angle of rotation by slider, also activation key can be rebinded.
Module can be also rotate, to do this select module and press [M] or Rotate button.
Edges can be also (like at plate) visible and collide-able, select it and chose isVisible checkbox
Plates and edges can have different materials, they can be chose by menu on right, material have different mass.
New things: -all element will be have a new, better model -wheels have own suppression -new GUI of editor is easier to use -new element Hinge
