Killer Instinct Classic 2 is a port of a classic arcade/Nintendo 64 fighting game developed by the legenday Rare from the late '90s, previously known as Killer Instinct 2 or Killer Instinct Gold. The game is similar to the original Killer Instinct in many ways; in this installment classic characters such as Jago, Orchid, Fulgore & Spinal are pitted against newcomers like Maya, Kim Wu & the evil Gargos. Players much punch, kick, cut & C-C-C-COMBO BREAK their way to victory against the AI, their friends in local co-op or online opponents. Note that this game is only available if you purchase Killer Instinct Season 2.
Step 1 - Arcade Mode:
The first step in completing Killer Instinct Classic 2 is to play through the arcade mode and defeat Gargos with each character in the game. There are 10 characters, so you will need to beat Gargos once with each character. Dying during an arcade mode run will not void the achievement for beating Gargos with a specific character.
Step 2 - 40 Wins with Each Character:
The next step is to get 40 wins against the AI with each character; you'll need to playthrough the arcade mode with each character a couple times. The game tracks your progress for these achievements so keep an eye on them while doing this.
Step 3 - Mop-Up:
Now you'll just need to get the miscellaneous achievements like "Just One More!," "True Survivor," as well as others.
Killer Instinct Classic 2 should be an easy 1000for people who've played this game in the past, though it might prove to be somewhat of a challenge for newcomers. But if you keep at it and learn the game you should eventually get the completion. Now go out there and fight!
