I was surprised by Blacklist, it's a lot of fun for a Tom Clancy game made post golden era. The story is alright in single player, nothing to write home about. Love all the weapons/gadgets you can unlock by playing, with the need to earn virtual money to buy each one, I spent a lot of time re-doing missions/co-op to earn more money for all the items. Re-doing missions with different loadouts or going different playstyles is a lot of fun.
The co-op missions are even better online, and a lot of fun. Just wish they had built in VOIP as it's sometimes hard to tell your teammate not to do something stupid.
The PVP multiplayer is kind of meh. Yes they brought back spy vs mercs but it just feels very unbalanced and unfair at times. It really comes down to being a spy, hiding in a shadow, run up to merc, press x, boom merc is dead, rinse repeat. Gets old.
OTHER than that, the CO-OP is fun, the single player is fun, and it's a lot of fun unlocking everything and re-doing missions. Well worth it for less than $30. (check Ebay, you can usually buy a key from there for around $20)
