By the time Segadiscontinued the Dreamcast in 2001, the PlayStation 2 was deep into its run of domination of the sixth generation of consoles. As Sega transitioned from hardware to software, they showed exactly why they are one of the best companies in the entire industry. Their impressive collection of PS2 games speaks for itself, featuring some of the toughest and most challenging games of the entire generation.

And much like Sega has always done, they did it while showing their versatility. They didn’t just make a bunch ofSonicgames, rather they showed how much they could innovate and re-invent themselves by cultivating a roster of PS2 titles from different genres. Whether it was action games, RPGs, or platformers, Sega flexed like no other during this generation with some truly difficult and challenging games.

Sonicfirst began making his way to rival platforms during this generation. BetweenSonic Advancefor the Gameboy Advance and a slew of titles on the Xbox, PS2, and GameCube,Sega was keen onkeeping the train goingby developingSonic Heroes. Introducing several new systems that would become staples later, like the Boost mechanic,Sonic Heroesfeatured four playable teams of three characters.

Each team represents a different difficulty level, a unique way of doling out challenges for the player. The courses and stages are fast-paced, furious thrill rides that culminate in some spectacular boss battles. For all of its 3D efforts,Sonic Heroesis perhaps the one that gets overlooked the most, but it is still one of the best and most challenging entries in the franchise.

As far as Sega fighting games go,VF4is easily one of the toughest and simultaneously rewarding.

A hallmark of any good fighting game is a sense of skill and progression that comes from practice and learning its intricacies, something thatVirtua Fighter 4does exceptionally well. During a generation that saw the likes ofTekken Tag TournamentandDef Jam: Fight For NY,Virtua Fighter 4was the ultimate showcase of their ability to create a deeply challenging and hard-to-master fighting game better than perhaps anyone on the market before or since.

Based on a Japanese manga series calledDororo,Blood Will Tellwas one of thePS2’s most forgotten action gamesand yet it feels like a strange sort of precursor to what the Soulslike genre would become. Taking control of a man named Hyakkimaru, a warrior who had his body parts stolen by demonic fiends, this unique hack-and-slash game was focused heavily on boss battles.

Featuring over 40 bosses, known in the game as “fiends”, these intense battles make up the bulk ofBlood Will Tell. Some of them rank up there with the most difficult bosses on the platform, ranging from huge demonic creatures to smaller, more nimble monsters. It’s a wholly unique and intensely challenging experience that is sadly forgotten today.

Acting as a sequel to the 2002 gameShinobi, itself a reboot of the famous Sega series,Nightshadewas released justone year later and sought to continue the intense and harsh game design philosophy of the first game. Enemies are quick and fearless, often surrounding and cutting off paths of escape until the player is forced to deal with them.

The bosses are also a highlight, ranging from agile ninja and sword-wielding humans to gigantic creatures. Additionally,Nightshadefeatures great use of platforming and the main character Hibana’s dash move. In conjunction with wall climbing and the perfect feel of movement,Nightshadeis still one of the PS2’s greatest tests.

By the time this brutally difficult action game came out in 2002, theShinobifranchise had been dormant for nearly seven years. But while this new version of Shinobi appeared different, it retained the series' trademark reliance on tough and sometimes outrageously difficult design.Shinobiintroduced a new lead, Hotsuma, replacing Joe Musashi as he embarks on a quest to avenge his fallen clan against Hiruko.

Initially planned for release on the Sega Dreamcast beforethat console was discontinued,Shinobifocused on battles where Hotsuma made use of a unique targeting system that allowed a soul-powered sword to increase in power with each enemy defeated.

Shinobialmost acted like a puzzle game in some ways, where defeating enemies in order to up the damage output of the sword was crucial, while also forcing the player to think tactically about their next move or face utter defeat.Shinobipulled absolutely no punches and is one of Sega’s hardest games to this day.
