The game offers training missions and actual missions. In the training missions, the player is trained for the basic activities.
Much of this game is making tradeoffs with time and resources. For example, you need a fixed number of engergy crystals to complete a level. You can use some of them to obtain drilling vehicles, or special buildings to supply air and food, or help locate crystalls. Rock Raider can hold a fixed number of tools. You can have some of them carry weapons to defend you mining base, but then they can't hold as many tools.

This is an interesting game that gets increasingly challenging and makes you think at times.

LEGO + mining in caves + Pikmin + Your Computer = LEGO Rock Raiders!

It is fairly easy, and you can get different views, and there IS a first person view by clicking on the button to the right. Keep clicking on things and it wil be easy to play. Sadly, the second or third level is very hard and until this day, I have never completed it. There are too many levels, and if you happen to manage through them, you must've counted 5 months. There should be a money prize for completing this difficult task of completing the entire game! Anyway, just point and click on your Rock Raider to do a certain command, and away he goes! Sometimes, they are busy doing something else, so just wait until he is done. There are many fun features:

View(first person, above view, ect.)
Feed Rock Raider
Name them!
Upgrade them
Put on an alarm!

And you can even make em' drive, but I have not got to there yet, but you can.

It is a good-buy for a cheap price of this.
Overall, pretty fun game, but challenging.
The graphics are good, (pretty impressive, I'd say), the sound is a 4.0, the music is 3.5, the control is a 4.0 for when RR's don't listen, and everything else is okay.

So, buy it, it is worth a cheap price, and you will be there for hours on the challenging level, so have fun with the new LEGO game!
