Well, better late than never I always say. So here we are - a month later - with the second and final half for our complete Space Age walkthrough.

As before, this is a strange mash-up of adventure game, sneak 'em up, action blaster, and strategy game - all wrapped up in a quirky retro-futuristic sci-fi narrative about landing on an alien planet.

In these last few missions we'll be figuring out what went so wrong on this foreign space rock, and hopefully work to put it right again. Follow our guide carefully to finish all the puzzles and complete the game.

Mission 11 - Against All Odds

Space Age

First things first, select the astronauts at the top and bottom of the screen and send them to the east to meet up with the guy in the car. Trust me.

Space Age

Next, select Miss Archer and wait for your command. When you're told to activate the portable console, use the computer in the top left corner of the building.

Space Age

When you're told to hit the sterilisation chamber, use the big device in the top right corner. Then when it breaks, use Kowalski (the engineer chap to the left) to fix it. Your astronauts should be able to fend off the aliens.

Space Age

You need to find a spare Nucleo-Card. There's one in a building to the north east, but take some astronauts as backup as another alien will come and shoot Kowalski in the back.

Open the door with the switch and use Kowalski to get the card. Return it to the sterilisation chamber and use the field medic to heal any astronauts who are hurt.

Space Age

An alien is about to come from the North, so send your astronauts to the top of the building to fend them off. Then quickly go back inside the building and stand on the left to kill another alien.

Space Age

As Archer, head south and chat to the friendly alien to get some green goop. Then, go give it to Doc as medicine for private.

Space Age

Head south and enter this greenhouse building. Take a blue flower and use it on the blender to the left. Do the same with the yellow flower. Then use the blender to make some delicious green goop. Take it back to the doc to save Private.

Space Age

As Private, go south and face off against the army of aliens. Don't worry, you'll defeat them quite easily.

Bonus objectives

Mission Without Loss - Don't let any astronauts get killed during the fights. Roll back to the last checkpoint if anyone gets vaporised and try again. Keep everyone in groups and use the field medic to heal up anyone who is hurt.

Mission 12 - Fallout

Space Age

Go investigate the helmet.

Space Age

As Kowalski we need to get to this computer, which is to the north west of the nuclear warhead. You can go through with the other astronauts and use them to wipe out the aliens, or you can sneak through if you want to meet the bonus objective. Either way, use this computer.

Space Age

The next computer is actually just above us, but you'll need to venture left and then double back around to get to it. There's an alien nearby so you either need to sneak past when he's not looking or just put his ass on blast with your astronaut crew. YOLO.

Space Age

Our last computer is in the southwest corner of this compound. There's an alien stalking around for you to avoid or kill, and an entire room of aliens that you definitely don't want to mess with. Luckily they won't notice Kowalski if he goes to the computer, from above, alone.

Space Age

Use this guy to open the gate, then take your crew and roll north.

Space Age

The computer is here, past two dudes who can be avoided or killed at your discretion. Hey, I'm not judging you, Mr. Murderer. Now disable that fallback computer as Kowalski to finish this section and this chapter.

Bonus objectives

No Senseless Violence - Get through the mission without killing any aliens. Best bet is to take Kowalski on his own so you don't accidentally shoot anyone.

Mission 13 - A Stranger's Place

Space Age

Pick up the newspaper. Repeatedly try to walk over the nucleum until Private lets in and wanders across it. Once you get through to the main room look at the blueprint, the picture, and use the horn a few times. Also, use the newspaper on the horn to finish the bonus objective. Then give the newspaper to the man.

Space Age

Time to make an apple pie. Go to the kitchen and get the recipe book. Take a knife and use it on the apples. Take some water from the sink and some flour from the side and use them both in the bowl, and then mix it by using the bowl.

Take the rolling pin and use it on the dough. Place a crust, then the apple filling, and then the second crust into the pie dish. Take the pie, open the oven by using it, and then put the pie in the oven. Take the pie out.

Space Age

As Talby, go south to find ROBBY-1. There's some nucleum on the floor just north of ROBBY-1. Take it, and return it to your broken robot pal.

Space Age

Go back to your ship to get a wrench and use it on ROBBY-1.

Space Age

Talk to the aliens and then use the nucleum you get on your robot servant. Talk to the aliens again.

Space Age

Go to the north, chat to the kids running around, and then ask this child for some nucleum. Use your bubblegum on yourself, then put the sticky goo in the jar. Use the jar on the fireflies to the north to make them follow you, then give the jar to Buckaroo. In return you'll get some nucleum.

Space Age

Start to go north, then keep tapping Talby to advance the narrative. Then watch the cutscene to finish the chapter.

Bonus objectives

Patience & Prudence - After looking at the horn on the cabin wall a few times, use the newspaper on the horn to play a special song from your past.

Mission 14 - Lord Servant of the Castle

Space Age

Have Archer press the switch just as the robots are in the top garages, and then quickly have Kowalski walk over to the left. As he's going, switch back to Archer and then repeatedly press the switch so the doors shut as soon as they open. If you get it right, Kowalski will be safely on the left, and Archer is out of harm's way on the right.

Space Age

As Kowalski go south and then sneak past the aliens to the switch on the right. You'll need to walk right, then go down, and then right again - avoiding the patrolling aliens at every turn.

Space Age

When you get to the button, copy what you did before but this time with Kowalski pressing the button and Archer running to the left.

Space Age

Go back to where you came from with Kowalski, and then have you and Archer press the buttons in this northern section at the same time to open the gate. Send both characters through.

Space Age

Next we're going to play as these four scouts. Go north and kill the alien duo. Then go up and kill the other aliens, but be wary of the laser turrets on your left: they'll murder your scouts in one hit. As long as one scout is left alive you can continue up and press the button to let Archer and Kowalski through.

Space Age

Take control of Kowalski and then use the four machines in the room with the scout(s) to turn off the instant death turrets. Have Archer, Kowalski, and any alive scouts head left, past the deactivated turrets.

Space Age

Look at this computer and you'll get an error message print out. Use it on Archer to read it, then give the message to Kowalski. Now use the switch as Kowalski to fix it and open the door on the left.

Space Age

Now take control of Private. Go north, kill all the aliens, and wander through the gate you just opened.

Space Age

Okay, boss battle time. First things first, kill all the tiny robots. Don't let them gang up on you, like above, or you'll be killed. Take them on one at a time until they're all dead and run away when your health is low to give it a chance to regenerate.

Space Age

Give ROBBY-1 the runaround until he's out of energy and returns to the base (you'll see the red meter on the right deplete). Then defeat the second round of mini robots.

Space Age

Once again, give ROBBY-1 the runaround and defeat his mini robots. But this time, there's a door open in the corridor that our other team members are in. You need to send Kowalski in and have him turn off the big red nucleum reactor. It's a bit of a juggling act, but you can do it.

Space Age

Now, the next wave of junior robots won't be brainwashed and will fight alongside you make it a piece of cake to defeat ROBBY-1.

Space Age

Go north. Grab Talby and Private and head down to finish Space Age. Congrats! That was a tricky one, eh?
