In the No One Lives Forever demo, if you laughed at the HARM goon falling from the sky without a parachute towards a barn while crying “please be full of hay, please be full of hay” you'll be glad to know that it's just a taste of the humour to be found throughout the game. You'll often come across two conversing HARM guards and these conversations are frequently oddly amusing. One time I listened in on one guard discussing how he was redecorating his room with the help of his mother, painting the walls a nice shade of off-white. Another time two guards were reminiscing about a now sadly defunct terrorist organisation and “that incident with the giant laser” that failed as they hired non-union engineers. Hearing these criminal hirelings talk about their everyday lives and other criminal organisations so casually is invariably amusing and a great idea on Monolith's part that adds a lot to the games uniqueness. The game is also scattered with the odd visual gag (“Use more wood! It'll grow back eventually.”). All this humour along with the classic 60s spy theme could easily have made for a cheesy spoof of a game, but instead it all blends together nicely so the humour acts as welcome comic relief that complements the rest of the game well.

With all these aspects to the game being so well done, the only area that remains a potential let down is the sound, and as it happens it turns out to be far from a let down. The main characters are all voiced perfectly during the many slick cutscenes and while the foreign accents of some of the enemies could've been a little more realistic, they're at least pretty damn convincing which is a lot more than I can say for some other games, and since No One Lives Forever doesn't always take itself totally seriously it's hardly an issue. Music throughout the game could've been lifted straight from one of the numerous 60s spy or detective movies, although having seen a few I have to say that it's much less annoying and in fact rather good indeed. The music also changes depending on the situation, so when the bullets fly the action music will kick in to replace the quiet music that accompanies you while you remain as yet undetected by enemies.
