After reading the development story, I gave this game a shot. It's not the worst game ev, but it's not very good either.
I hate the two "sidekicks" you have during the game. I don't hate the idea of co-operative gameplay; I mean I love Left 4 Dead. Daikatana, I think, was the first game to include co-op gameplay into the game's main story and singleplayer campaign. But the AI is just so stupid, and your sidekicks get into your way, and they say stupid one liners like: "I think you just need to put one foot in front of the other..." just too many times. And the Japanese woman talks in such a fake accent. "Eee Lowks Luyk samting out of te Tark Aches!"
I got this game off Gametap for 99 cents, and well, it is an interesting game, not a good one but an interesting one. It might be worth a free download, give it a shot if you had time. Content wise, the game ain't that bad. It has 24 weapons and many different, but all equally ugly, monsters. The real problem is that it doesn't matter if your enemy is a werewolf, a futuristic mechanic frog, a Roman soldier wandering in Ancient Greece, or even a future Alcatraz prison, all they do is just run at you and hit you, o bite you.
If the game had better visuals, better environments, a more solid story, and a much better AI, it would've been one of the best games ever. I guess it has just too ambitious, having 24 weapons and 30-somethign levels in 4 very different enviroments and tens of different enemies, and they started working on this game 11 years ago, when the standard number of weapons in a shooter was 5 or 6. Someone had to tell Ion Storm people preffer to play through a short, repetetive but good game, like Left 4 Dead, than a long, long, varied mediocare game.
