2Cross - a mobile bridge building game

2Cross is a J2ME MIDP 2.0 application which simulates a bridge constuction. It is similar to the desktop games bridge builder, pontifex and bridge construction set but is run on a mobile phone instead of on your PC.

The game

The game is a 2D bridge building simulation game. Your mission is to build a bridge between two locations. To do this you have different materials which have different properties and different costs. The challenge is to make the bridge as cheap as possible. There are 10 levels you have to finish to complete the game. There is also cooperative multiplayer where two of you can build the same bridge and together you must finish the levels or versus multiplayer where random levels are generated and the player that completes the bridge first wins.

Hints

Here are some hints that might help you in the game.

  1. Notice that there are multiple types of materials available. The icon in the lower left corner shows you current material. Materials:
    Wood Wood girder. No track. The train will fall through this girder.
    Wood with track Wood with track. The train will use the tracks on these girders. Note that this material is more expensive and heavier than the standard wood girder.
  2. It is necessary to change the grid size to finish some of the levels in a good way. Use the menu or the shortcut key to change the grid size.
  3. A simple constuction is usually the best construction. Levels in the game can be completed with much less than the available budget. Try different techniques.
  4. When you get to the higher levels you are presented with new materials. Some of these materials have properties you can control during simulation. Use the arrow keys or the menu to control them.
