City Siege 4: Alien Siege

Enjoy offline platform shooter games and lead space marines to stop the alien invasion.

Humanity's expansion into space brings the risk of hostile encounters. In this offline platform shooter, command a squad of space marines, battle aliens, and gather resources.

Your main mission in this alien shooter is to rescue all civilians abducted by extraterrestrials from the station. Simply guide captured civilians to safety and collect jewels along the way. These valuable resources help you earn cash faster, enabling you to recruit new units and enhance their abilities. There are ten different unit types available. Begin with lightly armed fighters and unlock advanced units like a tank, a flier, and a mech warrior as you advance in the offline platform game.

Game features:

- Play action-packed shooting levels for free

- Gather jewels to earn additional cash

- Unlock 10 types of units as you advance

- Personalize your squad by naming units

- Use airstrikes, napalm, and medical support to turn the tide

- Earn medals by completing all objectives

If you regularly play platform shooters, this challenge is for you. To earn all three medals in a level, you must fulfill extra objectives—like avoiding any casualties and eliminating every spacesuit-wearing enemy. Here are a few tips: start by checking the platform shooter’s tutorial. It explains how to command your troops individually and in groups. The tutorial is brief and will quickly prepare you for the offline action game.

Next, target aliens when their backs are turned to avoid counterattacks. During intense firefights, aim for headshots to gain the advantage. If your troops take heavy damage, deploy emergency medical aid. Rescuing your space warriors is not only humane but also more cost-effective than recruiting and training new ones. So, if you love platformer games, take on the challenge and collect every medal in this action shooter.
