Look carefully at the following tutorial:
- Open Cheat Engine
- Select the Process, then select the browser you are wearing
- Then play the mission of stage 1
- Checklist "Enable speedhack"
- Replace Speednya be 0.0
- Click "Apply"
- Then the time will stop (or any terms Freeze Time)
- Then you could search for weapons in want without the chase time
- After the weapons found, you can "Unchecklist" "Enable speedhack" (because otherwise the unchecklist later will freeze and hold ^ ^)
