Battletoads became the canonical example of Nintendo-era difficulty — a beat-em-up with two-player cooperative play where the notorious Turbo Tunnel level failed the majority of players. Its visual creativity and animation quality were exceptional for NES hardware.
Rare's Battletoads combined creative enemy design, large sprite animation, and gameplay variety (racing sequences, climbing sections, brawling) with difficulty calibration that bordered on hostile. The Turbo Tunnel's rapid-fire obstacles required memorisation rather than skill.
Battletoads was developed by Rare and published by Tradewest in 1991. Its difficulty became so legendary that it spawned internet-era memes about calling GameStop to ask if they had it in stock.
