I got suckered into buying Operation Anchorage, I was pretty unimpressed. I enjoyed Fallout 3 quite a bit too, but this was a big disappointment. The gear you get at the end is nice (a stealth suit and a lot of other stuff) but the new content itself was tremendously mediocre. For one, the performance on the 360 was pathetic, it was regularly chugging at like 10 FPS. That and Fallout 3 is a really shitty FPS game, when you take it ONLY as an FPS game. And for some bizarre reason, Bethesda designed the entire Alaska simulation to play like an FPS. There is no exploration/roleplay stuff whatsoever, it's completely linear (as in ONE NARROW PATH the entire time), and you can't even rummage through crates and shit. Health is dispensed via machines that are scattered around the levels, and you can only interact with a very small number of predetermined setpieces. Enemies disappear when you kill them because it's a "simulation", which also means you don't take any of your own gear in with you.
Basically, it's a very craptacular 2 hour FPS game with VATS. Better than HORSE ARMOUR I guess, but shitty nonetheless.
Oh yeah, and the BUGS. I don't think it was playtested very well!! If you play it on the 360, you better complete "you gotta shoot them in the head" before you collect your rewards at the end of Operation: Anchorage, because if you don't, the quest automatically completes out of nowhere. There's a suit of Winterized Power Armour I think that triggers it, like if you pick it up at the end of the DLC questline, then the other quest is marked complete too, at whatever stage in the questline you were in. Also the elevator down to the military base where the simulation is located CONSTANTLY bugs out and traps you. Like it teleports you into the elevator room but then the elevator just doesn't move and the doors won't open. Usually you can hit the switch and it will send the elevator back to the surface, but it COMPLETELY bugged on me once and trapped me, so I had to reload. The AI totally sucks too, you ally units that you can "command" but it only entails telling them to GO TO POINT A at which point you lose control of them and they act on their own (re: badly).
WHY SO SERIOUS HAHAHAHHAHAAHAHAHAHAHAHHAHAHAHHAHAHAHAHAHAHAHAHHAA
