Spawning Portals?

While the crew was on the train, they have found some sort of note saying: "There are 5 portals that are spawning aliens in this entire planet, 3 of them being inside Vast City Land, one on a volcano and one in the center of the planet. There is a small base in abandoned land, which contains multiple tunnels, leading to 3 portals." They read the message, and Samantha was trying to reach the specified location, as she successfully did. The crew has left the train without getting caught by the police and went into the base. Larry has made a plan so that each person or two takes a path.

A few minutes later, Larry has found some ladders and discovered one of the alien-spawning portals. Larry gathered in the crew and destroyed the portal without getting caught. They have done the same thing again to the second portal.

They were also able to successfully do the same thing to the third portal, which was outside. However, the police have caught them, and the quantity of the police was huge. The crew has fought the police with only a few injuries, making the police become a failure.

Gadgerito wanted at first to go to Paradise City, the planet's main city, but he wanted to destroy the portal located on a platform in the biggest volcano, just so that he clears up the portals and prevents any more aliens from spawning in this world. But before that, they had to remove the bullet from Tito's chest.

Later on, the crew has explored the volcano. Gadgerito planned on creating a gadget that will forcefully make the volcano erupt, but it required 15 minutes to do so. He built the gadget, which is a volcano eruption catalyzer. During those 15 minutes, the rest of the crew ran off as quickly as possible while detecting if there were any aliens or not. 15 minutes later, Gadgerito has finished building the gadget, threw the catalyzer, then ran away as soon as possible and as far away as possible.

Gadgerito tried to reunite with the crew and then found them just a couple of minutes later. A few seconds after that, the volcano has erupted, destroying the alien-spawning portal, erupting the land nearby, and destroying the portal located at the edge of the volcano.
