Space Monsters is an open-source futuristic top-down shooter developed and published by Psonic using Game Maker 8 engine and the first game of the Space Monsters series. Originally, it supposedly be released in 2013, but moved to 2015 due to its creator's independent difficulties. As the expansion update of this game, it is released again with the demo version of the second campaign on June 9, 2015 and a fully expanded version one year later. The multiplayer edition of this game is soon to be announced.


This game a titular reference to Taito's 1972 mechanical game, but it was renamed as Space Invaders by Tomohiro Nishikado's video game theory, especially his superiors. And if the creator is interested in video games, he gave his game project an inspiration of Alien ShooterAlien Breed, CrimsonlandSpace Invaders, Alien Swarm, Half-Life, Doom and The House of the Dead.

Some creatures bear the resemblance of Space Invaders and virtual humans.


In the spectacular year 2025, people examine the scientific study of the Earth's surface, discovering the strange cosmic creatures. However, the legion of alien teleportation devices from outer space is coming to contact earth before they unleash the army of harmful aliens, launch the invasion against humanity and support the domination in our planet.

Now, humanity is in danger and the invasion has begun to overrun everywhere in the base of businesses and operations. Each operative has given a chance as the member of the marine-tasked military unit known as the Investigative Force to perform these operations: clear out offices, facilities, warehouses and experimental laboratories around the long passages of an abandoned complex where the teleportation devices have allowed legions of aliens to overrun and take control over the humanity. They are also required to go and get explosive weapons and other equipment to open up the sealed doors into these top secret areas, where they contain security systems and measures. Yet, there will be a stationary automatic gun turret available to take foes down. The government has given access to the most advanced weaponry available in hopes of solving the problem after receiving many casualties of the previous military assault.

The military survivors of the Investigative Force despite the defensive efforts to resist alien invasion and save the humankind from total destruction.

Expansion update

As the time continues in the next year (2026), when the previous alien incident came to an end, Syrax became the true antagonist of the second campaign and will continue the alien works after avenging its predecessor's death. However, another incident has started to investigate the cause of another aggressive invasion when humankind is in danger again. So Billmore and the rest of the Investigative Force must stop the one who is responsible behind this event before causing a massive overrun.


This video game features retro-styled graphics, some role-playing game elements and top-down view. The usage bar with the allowance of a variety of weapons, equipment and other items must be automatically appeared at the upper right corner of the screen. Below the layout, there is an experience bar, which allows the player how many enemies you just killed to increase points and earn more experience funds if the experience bar is reached to the maximum point, also for gaining more bio-mechanical implants to become superhuman. At the bottom left corner, a weapon system has differently separated numbers of ammo (upper left), clips (bottom right) and availability of each weapon (image at the center). At the bottom right corner, the mini-map automatically appears if you got a portable radar. Finally, at the upper right corner, there are displayed as the player's amount of health and the amount of an armor.

Through the experience of deadly missions with some top secret areas, the player can earn more currency known as credits by killing monsters or finding anywhere in the level, get more weaponry and ammunition and upgrade bio-mechanical implants to make the player's abilities powerful for survival, but there are many obstacles and hazards to resist and survive in order to finish the mission. In some missions without activating a generator, the player sees the dark places everywhere if the flashlight is equipped. another one is the target system, which has started with point blanking. In the other hand, the cross-hair is important to aim the target properly instead. Whenever the player attacked the enemy at first, then you will hear the combat music as the game's main use. Once the player obtained an extra weapon, it automatically equips but you can change it by using the number keys if some of them are available. While the ammunition clip of each weapon reduces only once, the player can reload by pressing the reload key if it has a little number of ammunition rounds or the system automatically reloads if it is empty. Whatever each weapon has a little number of limited ammunition clips from running out instead, then the player must locate through the place with extra ammo, obtain the weapon once you got, swap it into the one with enough ammo, find the secret areas, break the crates to see something inside or make use of a campaign-only item shop before performing the mission. Of course, if the player's health is low, then he or she requires more health by finding a medical kit or auto-healing with an amount of medical briefcases, which can be carried up to 5. Whenever the player lost a life, the mission resets to the start point, except in survival mode.

  • 3 playable characters
  • 18 types of monsters
  • Some role-playing game elements

Game modes

There are 2 game modes in this version.


Each campaign has a different number of missions to finish: 1 in the training campaign, 12 in the first story and 8 in the second story (21 in total) with different types of locations. However, at the beginning of the first mission, the player starts with a pistol as their default weaponry. Also, this mode always loads or saves the game progress whatever the mission you want to perform respectively.

To finish the mission, reach the goal point representing a big green circle for proceeding to the next one or defeat the final boss. As a result, the game shows you the parts of performance report: elapsed time, enemy kills, obtained money, earned experience, the number of collected items, trials and total points of 5 results. If you perform the current mission quickly in less than 30 seconds, then it gives you the maximum time bonus of 500000 points. If not, then you will receive a time bonus that is lesser than the default. Without committing retries, you will receive 100000 points per mission completion.

In addition to the expansion update, there is a new feature available in the next missions of each campaign called item shop, where you can buy things to re-fill the ammo of each gun, increase the level of each bio-mechanical implant, import guns, get extra lives, obtain equipment and see the display at the upper part to remember how much is your money, lives and experience points.


This mode is way better without restarting and saving or loading game data when the player is down. Monster variety was decent, although a few different colors might be nice to differentiate them more, and maybe a few more movement styles. The first thing is career, which would be finished in the maximum experience points by slaughtering all enemies while spawning at the sides. And finally in endless, it can state how long you perform the forever rampage against the waves of enemies until the main character dies. All weapons and other items will appear in the rooms for further evacuation.

An arcade flyer of Taito's mechanical game is known depicting on Psonic's first top-down shooter video game project.

Axl Jet Eno-Lee R. Baños, the computer game designer, had begun the development of his first top-down shooter game that would be made with Game Maker 8.0 since March 2013 when he was going to graduate the 3rd year high school and its inspirational title was taken after Taito's 1972 electro-mechanical game. Even though he's doing a lot of important things, it absolutely took too long for designing new levels unless the 12th mission of the first campaign would come. But instead, it would be released in 2015 right away while the days of his college life through NDDU (Notre Dame of Dadgianggas University) were moving forward. In addition, its game engine would be released as soon as in the future.

Expansion Update

The second campaign was announced by its respective creator in March 2015 and it was titled The Revival. As you will see the game's latest feed, the following additional features of this update are:

  • 8 new missions
  • 3 additional playable characters
  • New types of monsters
  • Revealing new boss
  • Modification of the first campaign
  • Item shop will be included
  • New storyline elements, especially in the second campaign
  • New changes of each weapon number
  • Sound channels
  • The plus sign will appear beside the 'Health" text if the player's health is lesser than 20

Actually, the demo version of the second campaign was available along with the full version of the first campaign. So it would come out with more extra missions rather than 4 when its creator announces the latest update.
