This game is just like the other two in the franchise (in terms of pros and cons), except this game has a smaller story. It's really cool how many character cameos happen in this game, which I think is a good detail. This shows Gearbox's care for making good expansions, instead of making simple cash grabs. If I had played Half-Life 2 first, I would probably have forgotten about playing these great games, so I'm glad I made the decision to play Opposing Force and Blue Shift beforehand.
