If you have played the first Lego Star Wars you will know exactly what this game is like. Your home place as in the first version is Mos Eisly Cantina where you can buy your characters and special extras. In Mos Eisly Cantina you can also customize a character. Lego Star Wars II includes episodes IV, V and VI (4, 5, 6). With 5 chapters in all episodes that makes 15 action packed levels, some short, some long. But there is always the inner secret to each level.
There are also Lego Minikit Canisters with 10 to collect in each level. When you get 10 canisters in a level you unlock a bounty hunter for Multiplayer Arena Play. In the Arena Play there are two levels (to my experience) Jabba's Palace and Tatooine streets (not so sure of the name). In Jabba's Palace you can do a deathmatch and capture the flag (the flag is Han Solo in carbonite). Another Multiplayer mode is Cooperative play where you can go through the levels together though which is most unfortunate is that you will need 2 game cards to do this, but in the Arena play you will only need 1 game card as that version of multiplayer is DS Download Play.
