Over the course of its nearly decade-long development,
Too Human became obscured by a fog of cancellations, platform shifts, and even lawsuits. Our view of the game finally cleared up with the arrival of a nearly complete build. Now that we've seen and played Too Human extensively, we'll give an in-depth breakdown of each of the five character classes and our hands-on impressions of multiplayer co-op.
Berserker
The Berserker favors fast, close-quarters combat. They're the only class in the game that can dual-wield swords and staffs, and they back that melee power up with a devastating Rune attack that unleashes a crushing blow from a summoned spirit bear. Fighting a group of enemies plays out like in an ultraviolent version of connect the dots as you slide from foe to foe, dealing out crushing combos to anything in your path.

The Berserker's skill tree begins with options that improve attack speed or your combo meter's growth rate. From there, the skill tree branches out, opening up three paths with unique skills, abilities, and bonuses. Once you start down one route, the others become unavailable, making it especially important to select the path best-suited to your play style. However, to allow room for experimentation and to keep you from worrying about making the wrong choice, you can reset all your earned experience points and respec the skill tree at any point in the game.
Some of our favorite Berserker skills include boosts to slide damage, explosive mines, and an extra level for your combo meter. Likewise, most of the options complement aggressive battle tactics; they focus on using your superior speed and power to quickly build combos and unleash ruin attacks to make quick work out of large groups. Because of its extremely offensive bent, the Berserker makes for a great class to play solo.
Defender
As the in-game A.I. advisers, the N.O.R.N.S. (that's Non-Organic Rational Nano Systems), perfectly describe, "The Defender is the backbone of the Aesir's defense." A damage sponge, the Defender's purpose is to take the brunt of an oncoming attack -- and with it, occupy the enemy's attention so that his partner can hack or shoot away unmolested. His skill tree offers a variety of paths to help you "take one for the team."

For the Defender, the foundation of the skill tree starts with boosts to overall defense. Building on that, you can then develop ice-based attacks, damage-reflection abilities, or a taunt to enhance your ability to attract enemies. Because the Defender's equally weak in both long-range attacks and melee combat, a viable offensive tactic is to alternate between the two; thin the ranks at a distance, then clean up in close-quarters combat. But here's a better option: Play cooperatively with a strong offensive class like a Berserker or Commando, as the Defender's incredible ability to take a punch makes him the perfect teammate.
Commando
What the Berserker is to furious melee warfare, the Commando is to tactical, long-range combat. He specializes in explosives and spiders (small drones with a variety of attack and support functions) used in conjunction with a skill tree that improves reload time, range, and attack power. Digging deeper, there's plenty to get excited about, with everything from point-defense turrets that shoot down missiles to extended range for your rifle.
Whatever path you choose, the Commando's strength in ballistics ensures that you're most deadly from afar whether you unleash hell with rifles, lasers, plasma, or dual pistols. While all the shooting makes this class plenty enjoyable to play solo, the Commando does struggle with overwhelming groups on his own; his true potential is only realized in co-op.
Bioengineer
The Bioengineer specializes in healing; like the Defender, he can absorb a lot of damage. As with all of the classes, you can choose between a cybernetic or human path of development. The cybernetic path focuses on maximizing the damage per second you can deal out and allows access to bonus weapons and health. If, on the other hand, you decide to go along the human path, you can customize your items and tailor them to suit your style while also gaining an additional combo level.
The Bioengineer's skill tree offers several unique to ways to spec your character. One of his abilities, Skuld's Embrace, may charm enemies into changing sides so that they start attacking their allies. This comes in especially handy for battling your way out of a large mob of enemies. You also have the option of using your spider to send out an EMP blast to disable mechanical enemies, heal allies, or deploy a protective shield. The Bioengineer also receives a Battle Cry ability that can be developed in one of three ways: sending out a large healing wave, clearing negative effects, or enhancing offensive stats.

With his combination of skills for achieving max DPS while protecting a friend, the Bioengineer makes a great partner for co-op play, especially when paired with either a Commando or a character equipped with leveled-up ranged weapons.
Champion
In contrast to the specialization of the other classes, the Champion offers a balance of offense and defense. While he doesn't excel at any one skill, he doesn't suffer from any deficiencies, either. Attack-minded players can develop the ability to deal out damage with either melee or ballistic attacks, depending on how you spec out your skill tree. For instance, if you max the Asgard's Fury ability (increasing your air melee attack damage), you can wade through scores of enemies while hardly touching the ground.
During our playtime, we concentrated on leveling up the Champion. It's sometimes shocking how much ground he's able to cover and how much damage he can dish out as the game goes on. With his versatility, the Champion makes for a stellar co-op partner no matter the other player's class.

Co-op
Everything went smoothly in the sessions we played; only minutes after signing on, we were running around together in the game's first level, the Hall of Heroes. The experience is somewhat streamlined, in the anticipation that you'll be playing through multiple times. The additional bear and wolf squads that join you in the campaign are gone, as are the cut-scenes and tutorials. The first wave of enemies ambushed us within moments of the game starting, and we immediately noticed that not only was their location different than in the single-player game; but there were also a whole lot
more of them. The enemies also scale to match up with the highest level member of the party. This keeps the competition coming, but it also made it hard to team our level 16 Defender with a level 32 Champion. Often, the Defender was forced to hang back and wait for the Champion to make a dent in the herd, as the Defender could only handle a few blows from the stronger, higher-level enemies.
Still, that takes nothing away from how much fun we had playing together with two characters of roughly the same level. And on the technical front, we had a positive online play experience, encountering little to no lag and voice-chat problems; no matter how frenetic the onscreen action got, no ugly, debilitating networking issues raised their head. Too Human appears to be right on track to satisfy everyone looking forward to late-night, rare-drop dungeon runs.
