A huge disappointment. Avoid unless you like tearing your hair out.
The graphics are dated and unspectacular. Many of the sub-missions are near impossible to complete because using a keyboard is a hindrance to anyone attempting to get 15+ hit combos in to get bonuses. The game is of course geared toward children, but children easily would be put off by stupid little things that were ported from a console to PC and make little since.
It will be a miracle of someone unlocks all of the content in this game without ripping into the game's files. It's just that stupid for PC.
Much of the scoring I did is in regards to those interested in unlocking the game 100%, which is near damn impossible. For those who wish to go from level A to Z, it wouldn't take you more than a day of playing (and maybe 4-5 hours at that).
Earth to companies churning out cheap POS console ports to PC -- please evaluate the system you're porting your games to and make adequate changes. The only redeeming quality about this game is the fact that you can play as Mercer and kill Davy Jones. Sorry, thought I'd interject a personal opinion. Oh, and Beckett's actually one of the better unlockables. /2cents
