Planet Blupi (Planet Eggbert)

A delirious spell-binding game

Planet Blupi (known as Planet Eggbert too) is a strategy and adventure game. It subtly blends action with thought-provoking challenges. Behind the quiet and gentle facade, you'll enjoy a fascinating diversion full of surprises. Planet Blupi is ideal for ages 12 to 99.

The game was freed (source code and all media files) and ported to all major platforms (Linux, macOS and Windows) for it's 20th anniversary.

An HQ version is planned with higher resolutions and much better image quality in a near future. The current release (that you can download from this website) has mostly the same look and functionalities that the original version of 1997 but with a portable code and some bugfixes.

Blupi leads a quiet life on his planet until a strange meteorite crashes in a desert area.

Only much later does Blupi realise that his crops are being destroyed by huge spiders. Though he's always been a tough and healthy type, a weird virus has been causing him to sneeze and cough a lot lately.
What's going on ?

In fact, the meteorite is a spaceship. The only passenger on board is a mean-looking robot. Its goal is to build factories that produce a variety of aliens. Help Blupi use the resources of his beautiful planet to chase these invaders away !

The game

There are some 30 missions to figure out, ranging from really easy to completely mind-boggling.

The goals of the missions are varied: to grow food, to find a strategic point, to eradicate aliens, etc... You may need just one Blupi to accomplish the missions, or dozens !

  • Help Blupi to explore
  • Cut trees to produce boards and planks
  • Transport various materials
  • Build houses
  • Grow tomatoes
  • Pick flowers
  • Survey the ground
  • Extract iron ore
  • Devise traps
  • Throw bridges
  • Cure friends

A cool interface

Planet Blupi's interface is designed to remain as discreet as possible, so you can have fun and concentrate on the game. There's no need for long strokes across the screen with the mouse. You don't waste time choosing buttons and artifacts from a large display somewhere out of reach.

A small zone on the left gives general information about the mission in progress. When you want Blupi to do a specific action, just click on the right spot in the scenery. A palette of actions available pops up, and you can make your choice. Actions are smooth and quick.

A limited series of optional exercises can be used to learn how to play the game.

A large selection of decors

Blupi's planet has 4 distinct areas :
  • Open prairie
  • Deep woods
  • Desert
  • Snowy landscape

Each mission is carried out in a vast area of 40'000 cells (200x200 square elements).

You can even allow you to draw the scenery, set the goals and create your own missions.

What's new since 1997

This new version (since v1.9) is directly based on the last public release published in 1997. The rewrite was done in order to remove completely the dependencies on MS Windows and DirectX. The old code is based on Visual Studio 5 (a very old environment and compiler). This new version is based on the SDL2 libraries and supports at least three major operating systems and is built only with GCC or Clang. The MSVC toolchain is no longer supported because the dependencies handling is more painful that using MSYS2 under Windows.
