[TOMT] [game] [2000s] I am trying to find a game from my childhood that I barely remember and have little recollection of.

Okay, so what I remember from the game is that we are some military, and there are robots. We are on this island, and with me is this girl, who dies (sacrifices herself) at one point. But we meet her in this train tunnel, in a cave. In the game, there are cars and ships that we can ride. There are guns and all that shazam as well. The robots are red, and our primary color is blue.

Sorry, English is my third language, and I am not proficient in it. I doubt anyone can find this, but I have very fond memories playing this with my brother, who is no longer with me.
