World Builder World Builder is an online LEGO game , previously on LEGO . com . It was removed from the site , but can be downloaded from here : http : / / biomediaproject . com / bmp / lmp / games / ( in the folder Part 3 ) . It is set in a grassland - themed world where the sky changes depending on the world . The base game originally had only World 1 , but World 2 and 3 were added soon afterwards and an Ocean World and a Prehistoric World were then added to the game as challenge worlds . There are 60 missions in total in this game . Models . There are many models ( a . k . a . units ) in World Builder - a total of 20 , with 13 being land only , 5 being water only and 2 being amphibious . Monsters . These are models which are in the game always from the beginning of the mission . They walk in a random direction every second until one of your models is in their line of sight , at which point Building Models . The official help section on how to build models is as follows : " To build a model , you must first have a building PLAN for it . Your current plans appear in the window at the bottom of the screen . When you click on a plan you will see the bricks you need to build it . Move your cursor around the map until it ’ s near the bricks you need and then click to build the model . " " You can take models apart by clicking on the TAKE APART button and build them again . Or build a different model using the same bricks . But be careful , because every time you build a model you use up 1 plan . " Controlling Models . The official help section on how to build models is as follows : " To select a model , click on it . A bouncing arrow appears above the selected model . You can move the selected model by clicking anywhere on the map . " " Different models can travel over different kinds of terrain , so the selected model might not be able to reach the location you clicked . " " Some models have special actions , like carrying bricks around the map . To do a special action , click on the action button or press the spacebar . To learn about a model ’ s capabilities , click on the MORE INFO button . " Terrain . Normal terrain ( also known as land ) can be crossed by any land unit and has no hazards on it . It is always green in colour , and is the most common type of terrain . Rocky ( or mountainous ) terrain is harder to cross , and only a few land units are able to do it , including the Dirtbuggy . Rocky terrain does not harm the unit that is driving over it , but can be an obstacle if no available units are able to get across it . There is a third type of land terrain ( swamp ) , which is hazardous . Any land unit is able to travel over it , however , it will damage any unit that does so . There are two types of water ; shallow and deep . Units that are able to travel both on normal land and water are usually only able to go on shallow water , and not deep . Any water - only unit can go into deep water , except the Marina , which can only be built in shallow water . Water Crabs can travel in both shallow and deep water , but Alligators can only move in shallow water . A special type of terrain is the whirlpool . It counts as shallow water , and so can only be accessed by units that can move onto such terrain . The whirlpool will instantly transport any unit that goes into it to another predetermined whirlpool in the mission . They can be used for avoiding enemies , saving battery , and in some cases are necessary for the completion of the mission There are obstacles that appear in World Builder - the tree , volcano , boulder and sea rocks . Sea rocks only appear in shallow water and cannot be moved by any unit . Trees and boulders can only be moved by Treebots and Bulldozers respectively . Parts . In World Builder , there are different parts in the missions . These include Red Bricks , Green / Lime Bricks , Blue Bricks , Yellow Bricks , Batteries , and Tires . When building a unit , you use parts in the square it is being built in along with parts from adjacent squares . When a unit runs out of battery due to being attacked or you deconstruct it , the parts go on the ground . Batteries that are partially used up can be recharged by certain stations , but in most missions , there aren ' t any such stations . Batteries . Batteries are necessary for most units , with the exception of non - movable units other than Guard Towers . Each unit uses battery at a different pace , so a Treebot will expend its full battery much more quickly than a Defender . If any unit is attacked ( with the exception of the Defenders , Speedboats and Guard Towers ) , it will lose all of its battery and break in one hit . If it runs out of battery on its own it remains built but is useless . Batteries can be recharged by Robot Labs , Marinas , and Gas Stations . An enemy unit that runs out of battery will also be destroyed , although instead of a useless empty battery it will have a full one . Defenders ' and enemy units ' batteries will run out more slowly , taking " damage " with each attack . ( Please note : the batteries are shown in the what is needed to build each unit . It is the small , grey brick that looks like a washer with a " lightning " bolt on the front . ) Plans . At the start of each mission , you have a certain number of plans ( although sometimes you only start with a unit and no plans ) . You use these to make units and you have a maximum number . Throughout missions there are often plans at different and usually important locations , allowing you to build more of the units . Goals . The goal often requires you to reach it with a specific unit , or unit type , although in many cases any unit ( or sometimes an enemy unit , instead of your own ) will suffice . The goal is represented by an exclamation mark , and when you reach it you are given the option of doing the mission again , finishing , or doing the bonus " challenge " . If you do the bonus challenge , the flag that shows you conquered the mission will have a star on it as well . The bonus goal , represented by a star , is often more difficult to get to than the goal , and usually , requires different units to reach it than the original goal . Worlds . There are 5 worlds with 12 missions on each world . When you complete a mission , usually one or two more unlock , although this is not always the case . When you are able to play a mission , it appears with a question mark over it . Once you conquer it , the question mark is replaced by a flag . Completing the bonus goal will cause this flag to have a star on it . As you progress through a world , more and more friendly units appear on that world ' s map , moving around . This is a purely cosmetic effect . All the worlds have a sky background . World 1 ' s is during the day , World 2 ' s is the evening and World 3 ' s is at night . The Prehistoric World has a background consisting of many tall earth pillars with swamp at the top , and the Ocean World has a half - sky half - ocean background . World 1 . Missions : World 2 . Missions : World 3 . Missions : Ocean World . Missions : Prehistoric World . Missions : Licenses . Once you conquer enough missions ( with stars ) , you get a license . There are four different types . The first one requires 0 - 11 bonus mission to have been completed and gains you the title ' Class 1 Builder ' . The second one requires 12 - 23 bonus missions to have been completed and gains you the title ' Class 2 Builder ' . It has an image of a Frog . The third one requires 24 - 35 bonus missions to have been completed and gains you the title ' Class 3 Builder ' . It has an image of a Truck . The fourth one requires 36 or more bonus missions to have been completed and gains you the title ' Class 4 Builder ' . It has an image of a Defender . You must first complete every mission to see your license , and could originally choose to print it out . When you beat the Ocean World and the Prehistoric World you get stickers on your license . World Builder 2 . World Builder 2 is the sequel to this game . It includes newer models in the game , as well as some new gameplay aspects .
