When talking about elements of environment, I would like once again to emphasize the importance of different type of covers, which can preserve Hitman from being detected in countless situations. But that's not the only important matter. It is worth to mention mainly elements of environment, which can be used to distract opponents or even to get rid of them. In the first category we can list mainly radios and car alarms, so you should always look around closely to find any additional opportunities helping you in passing by enemies. When it comes to new ways of eliminating enemies, these are mainly proximity mines and remote-controlled charges, although in some locations you can find also a variety of devices (such as a live fence switch), which can be used to kill enemies (specific examples can be found in the game walkthrough).
