Found the Lime Pepsi Max - not very 'limey'.
It's strange that we have various citrus varieties of Cola over the years here, but in America everything is cherry flavoured (coke, pepsi, Dr Pepper).

And the Doritos Burn are very sweet... possibly to offset the hotness of it for regular consumers. Neither of these (limited?) flavours will be missed by me when they've had their run. I won't buy either again.
