Meta Worlds: Space Expedition

- Captain? The connection is getting lost! Are you okay?
- Captain?! What happened?
- We are sending our best troops to help you. Please, hold on.

The time when people dreamed of traveling to other worlds is long gone, with the appearance of space flights, and later, the Space Travel portals. Hundreds of lost civilizations were discovered throughout the universe, and now the main goal is to explore new planets and find out why they have been destroyed, along with excavating precious minerals and metals, which can be sold on the Black Market, in order to continue the exploration, upgrade the weapons, starships and build on the base.
People settle on these planets, build their bases to collect artifacts, and enforce them with turrets shooting weapons and tanks to protect them from diverse alien creatures and monsters.
Travel and explore the galaxy;
Defend your base with the ultimate military technologies;
Meet multiple alien species, and fight their bosses to protect your base;
Explore the ruins, find artifacts to find out the history of the lost civilization;
Excavate resources to upgrade your base and ammunition;
Follow the storyline, get orders from your captain and level up in rank from a simple soldier to admiral;
Open the portal and travel to different locations, reaching the Black Market for special weapons, rockets and vehicles;
Build up and defend your base, so you can open the mystical ancient portal and find out what is beyond.
Now, the base needs your help! It may be destroyed, and firstly, you have to bring back the connection with them!
