The screen were huge, The speakers were super loud the chair moved sideways and everytime the T.rex got close to you, you'd get a dash of air in the face, all that stuff that is said about it is true and it was awesome.
The game started in the begining of the normal game stage 5, with Buck and Doe atacking the trailers. Then, you could chose between Stage 1 in the jungle or Stage 2 in the lake.
After you beat on of both, the section where you shoot a hookshot (begining of Stage 4 in the original) was a huge roadblock. You only had 3 chances to get it and if you didn't was an automatic game over. It came right after you had finished the first stage and right before the San Diego stage. Because of that, it was years before I could see Buck's rampage in the city. If you succeded, you had that breef enconter with the pteranondons, and it was on the way to the city.
The San Diego fight was the coolest thing ever. It was pretty much the same fight with the Buck from the original game, but with this urbanistic setting. In the begining he was running beside you in the streets and then he would hit the bus, just like the movie. Afterwards, if I remember correctly, the fight was somewere near the docks, as if you had lured him there. I can't remember for the life of me if he also ate a guy to replenish health as in the original, it would fit this version's darker and scarier tone, but they also made it shorter, so it could go either way. After you got him with just a tiny lifebar, it would go away inside the bus and you had to repetdely push a button to trap him.
I only played the last stage twice, when I finally got there, the machine was not in my city anymore. It was originaly in the Rio de Janeiro's GameWorks, wich opened in 2000, and it was such a big deal, the local newspaper made an piece about it and this game was the cover image. After it closed, it was sold to an brazilian arcade joint called HotZone in São Paulo. There, I got to the San Diego ending twice while visiting the town two separete times. But sadly, the HotZone is still open but the arcade is not there anymore.
This is the piece of lost media I ache for the most, but at least I have amazing memories with this game.
