While I hate to diminish any sales Capcom might make on releasing this game to the PC, the majority of these comments are aboslutely correct. Bionic Commando is...not a good game. I bought it for $20 new, and I'm convinced I was effectively ripped off. It's a $10 game, if that.
GRIN actually implemented gameplay mechanics that are DESIGNED to frustrate, anger, and otherwise antagonize players. For example, every level has several collectible objects the player can go out of their way to pick up as well as challenges they can meet to receive rewards to their weapons and health, but if the player dies, the collectibles/challenges are RESET, making the player go back and get them again if they want a 100% completion rating. This is compounded by the player character being a complete pussy, with hardly any health throughout the majority of the game.
The swinging mechanic works but is also very weird. Your character maintains the same velocity during the scope of each swing, but at the arc on either end, it's like the character hits a wall of air, and slows to a stop in half a second. Then you swing the other way, and stop again. It's like they wanted to provide the player with freedom of movement, but not too much freedom! It also doesn't help that the levels are all essentially long tubes of terrain the player is allowed to traverse, but if you venture too far in any direction, you're quickly killed by "radiation", which is their convenient excuse as to why the game doesn't feature an open world - the city you're in was hit by a nuke, see.
The story KIND of makes sense along the way but then in typical Capcom fashion they just give up any kind of logical progression at about the 80% mark, zip you all over the fucking place to locations that aren't nearby anywhere you were with no explanation (at one point you're in the city, then in the next stage you're over the ocean, then in the next stage you're in a desert), introduce characters that do important things in two cutscenes and then never show what happens to them, and ends in a non-boss fight/cinematic. And the worst of it is, this game was developed by Grin, a third party development studio. I honestly expected them to develop the game their way and not the Capcom way, but I see that was a stupid thing to expect.
Multiplayer is fun for about 20 minutes, and then you realize it's exactly the same thing over and over and over again, just on different maps. It's a contest as to who can jumpkick the other players the fastest, and who can get to the best weapons the quickest.
The best thing about the game is the music, but that certainly isn't worth the full price.
