Alien Shooter (video game)

Alien Shooter is a top-down shooter game developed and published by Sigma Team in 2003 for Microsoft Windows. Later ported to iOS and Android mobile devices in 2013 during the series' 10th anniversary. It is the first title in the Alien Shooter series to be followed by Alien Shooter: Vengeance. Alien Shooter has two expansions, Fight for Life and The Experiment, each of which has five new levels and include the conclusion to the Alien Shooter story.

Alien Shooter Revisited is a new version released in 2010. It features ten missions; 9 weapon types; three game modes; modern visual effects; upgrading with help of implants; buying additional gear that carries over to the next level. However, the blood is lesser.

Plot
After contact is lost with an underground laboratory and several failed military assaults, the protagonist is sent to investigate. Upon infiltrating the complex, the player finds it overrun by alien creatures. The cause is discovered to be the experimental teleportation devices. Aliens have been pouring through the teleportation devices and are amassing within the laboratory's confines. As the protagonist goes deeper into the complex, more numerous and powerful aliens are encountered. Eventually, the protagonist successfully destroy all the aliens and teleportation devices in the laboratory. The final cutscene shows a single alien creature escaping the laboratory and runs away.

Gameplay
The characters have 4 stats: Strength (better carriage of each weapon's ammunition), Accuracy (better accuracy and damage), Health, and Speed. Players can start with a male character (stronger and has more health) or a female one (faster and more accurate).

Alien Shooter is presented in top-down view (3/4 perspective). The game consists of 9 levels with increasing difficulties. The objective of each level is to kill all the aliens. To achieve this, player need to access all areas of the level (by reactivating power generators, destroying walls, disabling force fields, etc.) and kill the alien creatures. Later levels have teleportation devices, which spawn enemies infinitely and can only be destroyed by special explosives scattered throughout the level.

The killed aliens drop pickups, consisting of money, health and ammo among other items. Between levels, players can purchase more powerful weapon in a shop. It is also possible to purchase permanent upgrades to the 4 stats. Temporary upgrades can be purchased include "Lives", Body Armor, Attack Drone, etc. Most items in the shop can also be found in the levels.
