From the intro text (original grammar intact):
You are a detective in a large city! A insane man has recently robbed a bank, killing three people and running off with one million dollars! You suspect that the criminal is hiding out in a old abandoned mansion! Your mission is to find the treasure and the money but beware, the criminal is waiting for you!!

That intro text reminds me of a 419 from Nigeria, especially as all the screen text will be in upper case so it really does say "ONE MILLION DOLLARS!".
Brilliant comment :)
