10 Celebrity Musicians Hidden In Your Favourite Video Games

While he may be more conventionally found in a title like Rock Band or Guitar Hero, veteran rock star and KISS frontman Gene Simmons is one of the unlockable characters in the skateboarding title, Tony Hawk’s Underground.

To unlock Gene as a playable character (as well as a KISS themed bonus level), all you need to do is clear the Story Mode on Normal difficulty. This will also unlock a number of other extra options, as well as the Tony Stark alter ego Iron Man as a playable skater.

As mentioned above, KISS are honoured in one of the more esteemed Tony Hawk games with their own bonus level called Hotter Than Hell (which is essentially what would happen if a rock concert and a skate park had a baby). Collecting all the K-I-S-S letters in the level will unlock a video of the band performing God of Thunder.

Proceeding to collect the same letters for a second time will cause an eerie chime to play, green flames to burst forth from the stage and all the band members to emerge from the infernos and play you your own live personal concert.
