## Gameplay

Alien Shooter is presented in a top-down, third-person view (3/4 perspective), and takes place across nine levels of increasing difficulty. The main objective of each level is to eliminate all the aliens. To do so, players must access all of the areas that the level has to offer (by completing tasks such as reactivating power generators, destroying walls, and disabling force fields, etc.) and removing the alien threats within. Later levels feature teleportation devices, which spawn enemies indefinitely, and can only be destroyed by special explosives scattered throughout the level.
Characters have four stats: Strength, Accuracy, Health, and Speed, and players have the option to play as either a male or a female character. Male characters have higher strength, and higher health stats, whereas female characters have improved accuracy and higher speed.
Once exterminated, alien enemies drop loot consisting of money, health, ammo, and other items. Between levels, players can purchase upgraded, more powerful weapons in the shop, along with permanent stat upgrades. Temporary upgrades can also be purchased, including "Lives", Body Armor, Attack Drone, etc. Most items in the shop can also be found scattered throughout the levels.

## Plot

In the early year 2030, scientist from M.A.G.M.A Energy Corporation created the bio engineering creatures by mixing both DNA animals and alien cells from a meteorite they've been found. Those creatures have been successfully created such as mutant frogs/spawn frogs, multi-armed bipeds/raptors, giant spiders, and tank rhinos. However, something bad happens, the aliens plan to escape from their cage while using a teleporter device as their plans. Protagonist's task to eliminated the aliens inside of abandoned experiment lab places. As the protagonist explores the lab, the root of the problem is revealed to be a malfunction with an experimental teleportation device. Somehow, the aliens have managed to flood through en masse, killing the scientists and guards who were working in the lab. Delving deeper into the complex, the protagonist encounters ever more powerful aliens and realizes that all the teleporters must be destroyed. The game reaches its conclusion when the protagonist has eliminated all of the aliens and destroyed all the teleporters in the laboratory.
The final cut scene shows a single female spawn frog escaping the laboratory and running away. The story is continued in the first expansion, Fight For Life, and concluded in the second expansion, The Experiment.
* Fight for Life: Six months after the events of Alien Shooter, it becomes clear that the alien creatures have returned. The protagonist must revisit the laboratory and is tasked with the mission of recovering and deploying a virus to kill all the invaders. After reaching the depths of the laboratory, the protagonist locates the virus but discovers that the aliens have already destroyed it. Nevertheless, the second assault on the laboratory forces the alien hordes to retreat.
* The Experiment: A few days after Fight for Life, scientists from M.A.G.M.A. plan to bio-engineer two brand-new separate species of "mutant dinosaurs" and "acid bats" aliens to aid them kill their previous creations. They succeed in creating the creatures, however the creatures go berserk and kill the scientists. The protagonist returns once again to eliminate the aliens for good. Alongside M.A.G.M.A. soldiers, the protagonist ultimately rescues the surviving scientists and recovers a sample of the creatures' DNA.

## Reception

In 2012, GameSpot gave Alien Shooter a 6.4 out of 10 rating, writing, "While the game makes good on its promise of giving you aliens to shoot, the result is very repetitive."
