15 Hardest PS2 Games of All Time

Contra: Shattered Soldier

Contra: Shattered Soldier is a direct follow-up to Hard Corps, especially in terms of the difficulty. Eschewing power-ups for a new weapon system that encourages switching, you’ll need to memorize enemy patterns and level layouts for the best approach. Keep in mind that this is with limited checkpoints and continues, meaning you’ll spend a lot of time retrying stages and bosses.
