About this game

"Alien Survivor" is an exciting game where players struggle for survival on a planet invaded by aggressive aliens. At the beginning of the game, players are given limited resources and time to build a base and prepare for the attack.

Key aspects of the game include:

Battles with Aliens: Players face various types of hostile aliens, each with unique characteristics and abilities. Depending on the difficulty level, players encounter a wide range of battles, from small skirmishes to epic boss fights.

Base Building: Players have the opportunity to construct and expand their base with various structures, such as residential quarters, production workshops, defensive walls, and more. Each new structure not only improves living conditions in the base but also strengthens defenses against aliens.

Resource Gathering: To ensure base production and development, players must gather resources such as minerals, energy, and food. This includes sending teams to scout and mine resources on the planet's surface, as well as managing their distribution and usage.

"Alien Survivor" offers players a unique blend of strategy, action, and survival in an atmosphere of an alien world, where every decision matters and can impact the outcome of events.

I really like the game but I'm leaving 2 stars because the rewards the the end of each round should be free and not stuck behind an ad wall. It's one thing to have an ad to multiply or somehow enhance the after round rewards but to force you to watch an ad or pay real money to get the goodies you just earned by beating the level is greedy and frustrating.

It was an interesting concept and I was real enjoying it until the game started shoving full screen ads down my throat for every 20 seconds I played the game. I get ads are your bread and butter but if you want people to actually play the game for you to get the revenue that you need don't chase them off with forced ads 3 times for every minute they play.

This game was interesting and fun for a bit. After a certain level, you will be forced to watch ads every 90 seconds, you can play offline to avoid this, yet you will not be able to gain certain rewards. Also workers on the second world stop working after their first crystal collection upon your arrival on the level. Your character is broken once you get to the max level, it reverts to lvl2 and you no longer can lvl it up. When, I got two weapons to lvl50, it broke the weapon upgrade window.
