I actually enjoyed OO2.
There are two ways to play it:
1) Charge in, get stars lobbed at you, die, restore, repeat.
2) Use a bit of stealth, sneak past the enemies, "Thief"-style, and be VERY careful. Oh, and remember that cameras can see through walls. There's a way of getting around the last part, but it involves modifying code.
(Note to Bramlage: Have cameras check #if blocked seek before sounding the alarm and sending the killer robots to wipe out the player.)
The second method is a lot more fun, but I suspect that most people don't try it. (I did, but frankly it was so tiresome and finicky that the game became even more irritating than it had been previously. - Funk)
The plotline is, as Funk mentioned, very, very weak, but this isn't that unusual for a ZZT game. The cutscene graphics are odd, and often sketchy, but have a bit of atmosphere to them that I found surprisingly... acceptable.
Whether or not you enjoy OO2 depends on whether or not you really, really like stealth gameplay, and don't mind severe logic lapses.
I took a break from adventuring like a demon on fire to play this game that these people seem to like. I thought an E.R. simulator, you know, brain surgery. I couldn't believe it when I pressed the P button on my shiny new keyboard that I acquired during my raid of the evil Office Max empire and execution of the "Man-a-ger", Jim Howard.
It was an introduction sequence. In green. All green.
Now, I've had a past of negative experiences paired with green. The evil ogres of lands neighboring daventry, who often attempt to raid my domain, are green. The poison plants of Ankor, which I had the unfortunate chance of meeting, are also a light green in color. When I saw this incredible overload of green, I instantly fainted.
The rest of the game was no picnic either. The "defenders" who chase after your happy white face resemble the hunchbacks of the Castle Barquane, who imprisoned me for weeks in their tower, feeding me only dragon feces and polluted water. After this incident, I turned my computer off, waited an hour, and turned it back on. Then, I deleted the game, never to even lay eyes upon the SECOND file of this horror.
I'm unsure if I would like to play any game by this "Chase Brambles" again, and personally, I hope he chokes on a raisin.
Imagine gameplay so frustrating that the only challenge comes from how fast you can reload your game. Imagine bad guys who spew stars at a rate of knots. Imagine a first screen so appallingly difficult that you'll wear out your "s" key saving with each goddamn step. Imagine a plot that could have been written on the back of a stamp and still leave room for a picture of a monkey smoking a pipe. Imagine a game so utterly tedious it makes plucking out each indidual pubic hair on your body seem like a more worthwhile way to spend your time.
Got that? Great, now you don't have to bother downloading this tripe.
