I went into this game with relatively low expectations, but it does a magnificent job of building on what was great about Conviction and making it better in pretty much every way. The fact that both my single player and coop progress help towards my same set of upgrades, the grading of your play style between ghost, panther, and assault. Finally I'm as big a Michael Ironside fan as anyone but the new voice actor for Sam Fisher does a really great job here.
An easy recommendation to anyone who likes action games, or enjoyed past games in the series.
