The PDA is full screen and in a brilliant stroke of game design is based around a common Web Browser. Directly beneath is where all the information is displayed. Datalink button , which gives access to all the files you require in your investigative journey. Newslink contains the fictional messages and news updates that the player will receive periodically. When you select a news item, it does not immediately display the video, but instead sends it to your mailbox as a video email.
Email regularly comes in with vital clues, or congratulations on an arrest.
Video communications come in from superior officers, and your colleagues out in the field send digitally recorded messages you can play back. Often messages have 'hypertext links', for example, if a colleague mails you with a lead, their name will be printed in a different color. Clicking on the name will automatically bring up the relevant information from the Datalink section. To progress in the game, most elements are puzzle based, and revolve around using a field tool. There are many tools at your disposal all of them modeled off a tool in reality.
