As title says, BRIDGE! The Construction Game is a game about building bridges across stream of water and not getting wet, similar to Pontifex series.
In each mission, player has to link road ends at river or harbour banks. For this, limited amount of various materials and certain sum of money are granted. The field, separated into 1×1 meters net, allows to connect parts freely, where joints can be one of three types: fixed, with sections rigid connected; break, without any connection at all; and rotating joint, when parts can rotate around axis. Wide components specter gives access to many sorts of road sections, girders, hydraulics and cables. Utilizing that rich choice, player is challenged to build truss, suspension, bascule, cable-stayed and other bridge types up to 300 meters long.
The main campaign consists of thirty levels, ten for each difficulty type (easy, medium, hard), with number of goals at the end. Basically, they are separated into traffic related tasks and natural disaster endurance: traffic might be cars, train or ship; disasters are presented with flood, earthquake and windstorm, each of three power tiers. At any moment, simulation mode can be turned on in order to test stability and perform trials. After successful completion, player receives new parts for free editor mode, which doesn't restrict anything and allows to place anchors, pillars, to change bridge height, length and, if constructed building withstands selected test, to save custom missions and share them with other players.
