Hello,
The solo campaign is short and quite straightforward but fun.
Online multiplayer is simple BUT VERY FUN (and addictive with friends), you can play as a team on former unlocked levels.
It's easy to find people to play with, you can mix friends and other people into battles.
But it's hard to recommend it because of the campaign solo and a lack of "normal" multiplayer game modes (death match, capture the flag) its only a race to high score killing bugs from outerspace, FUN but I wont play it a lot again and again because of the small numbers of levels.
But the good news is : if the game continue to perform well, DLC will be produce !!!! source : gonintendo
