my favourite idea would be to use the konami code - store the last 10 actions and if that full set == u,u,d,d,l,r,l,r,a,b then complete a "cheater" mission that provides a hint about cheat codes.
given a and b aren't supported verbs we'd probably want to trap these in cases where the previous 8 steps match,
a bit tricky just for an easter egg so low priority fow now
