About the game Clone Crisis

Well, it means that my nokia2322c has played through all the levels except the seventh level. I downloaded the Clone Crisis revised version . After passing the fifth level, the other levels will automatically open, but the seventh level will keep making errors, so it is better not to play! Also, when reaching the sixth level, pressing 0 when entering the elevator will cause an error immediately. I thought of a solution: Don't go to the elevator immediately after entering the sixth level. Walk around in this room first, wait for about five minutes, and then go to the door to guard it until the police fall down. Because his back is to you, aim your gun at the head and hit him with one headshot. After killing about three of them, slowly walk into the elevator. Press 0 at this time and the chance of making an error will be much smaller. Once you get in, immediately enter the mecha. The police are all carrying rocket launchers. If they hit you, you will be finished! It was the second level that got mixed up, and it took me a long time to pass it...
