Again this is one of those games that I'm sure people on the Internet, including the GR community have played, but I seem to be the only one out of all my "iRL" gamer friends who has played this game, let alone knows of it.
Hybrid Heaven
Hybrid Heaven was developed by Konami, released in 1999 exclusively for the Nintendo 64. It was a game played in a third person perspective, combining elements of an RPG, fighting game and action/adventure into the one game. It was also one of the few N64 games that required the memory card to save/load one's progress. The game also featured RAM pack support but unlike games like Perfect Dark or Donkey Kong 64, it wasn't necessary.
Without revealing too much of the plot, the game's takes place on Christmas Eve and revolves around "Hybrids". Hybrids are synthetic clones of humans created by an unknown source (the bad guys, basically). These clones were created to slowly be placed throughout the high levels of society, particularly politics and leadership to take control of the world. Your character gets caught up in all this, ended up in a massive, unknown bunker right beneath New York City and of course, has to inevitably stop it. The storyline is very sci-fi, with a mix of 80's action cheese.
My description of the plot is very far'fetched and "wtf", but it actually makes more sense and sounds better if you play it and go through it. I was just trying to avoid spoilers.

There's a heavy emphasis on exploration but it is a bit linear, considering most of the environment is just a variety of metal corridors and such. You run around, find items and that sort of thing. When you encounter an enemy, they'll usually run at you to try and engage a fight, or if you manage you can get a surprise attack from behind to begin the fight with an advantage. Some fights can be entirely avoided, sometimes they can't.
The player engages an enemy in a fight. Enemies can vary from humans, to Hybrids, to monsters, mutants and robots.
All fights are one versus one. When you fight, movement becomes different. You're always locked onto your target and you move in an eight direction axis, essentially circling the opponent. You can run, which disables your lock on and drains your stamina.
Before you can attack, your Power bar must reach full limit. If you attack when it's not full, your attack won't be as effective. When you move close enough to attack and press the attack button, the game will pause and then you'll make a choice of what to do. You can attack with a punch, a kick, or attempt to grapple the enemy to try and do something like a throw or take down. When you attack, the enemy can either try and dodge, block or even counter your attack.
When the enemy attacks you, the game pauses and you are given a choice. Counter, block or dodge. Blocking was the easiest but you would still take damage. Dodging was recommended if you had the distance, while countering is the riskiest but most rewarding, allowing you to hit the enemy right back and cancel their attack(s). The combat system is essentially turn based, to a degree.
As you win fights and defeat enemies, you'll gain experience points and level up like in any RPG. Your stats will increase and you can level up parts of your body to be able to do more damage, effectively making your punches, kicks and grapples more effective. It's up to you if you want to balance it out or be strong in certain areas. Personally my character was useless at punching, but was great at kicking and grappling, since kicks had longer distances than punches and because grappling was quite powerful.
You can also eventually acquire the ability to perform combination attacks, or combos. Your power bar can eventually increase up to five times, which can allow you to attack an enemy up to five times if you wish, dealing some serious damage. However, should an enemy counter you than the rest of your combo is cancelled out.
The range of attacks is very broad, to the point of being almost ridiculous. It wasn't just "Punch" or "Kick", it became things like "Right hook", "Left hook", "Right low kick", "Left high kick" etc. There was so many. The reason for this is because you and the enemy can both take damage in certain parts of your body, which means you or the opponent (if struck in a certain spot too many times) can effectively become crippled in certain areas of the body, meaning you'll move slower, take more damage on that spot and be less effective when attempting to strike with a crippled limb. It's also entirely possible for you or the opponent to be knocked unconscious during a fight, which if that's the case, means you or the enemy can beat the opponent to death while they're unconscious.
The combat system is interesting and it is pretty fun. It has a very funky 80's action movie vibe to it.

Hybrid Heaven also included a two player versus multiplayer. It wasn't that fun really, because all of the characters you can choose from are level one, with the exception of the main character who is whatever level he is in your campaign. Still, if you had a friend to play with who had the game as well, you can fight each other with your levelled up characters, since the game carries save data on the memory cards only.
The game had a pretty cool, almost cyberpunk style soundtrack. The game also includes some voice acting, mostly in just the intro and final cut scenes. As expected, the voice acting is pretty bad, but it's still kinda cool.
