Brütal Legend

This achievement is for riding/interacting with each of the beasts/animals.
Shock them with lightning to stun and then mount with the "Y" button, sometimes more than 1 shock is required to stun them.
All these animals are killed in hunting missions, so multi-task and do them at the same time.

The far left of the map has the Raptor elk, Razorfire Boar and Tollusk.
The iced area in the middle of the map has Hextadon.
The jungle contains the Laser Panthers.
And finally the Reaper Steads and Guillotar are further south of there.

You can ride the animals which you summon, but they don't count towards the achievement.

this is just a short video on how to achieve what the dudes above have said

Its smart to do this while you are doing the hunting misions.
Ride the animals you can while hunting and you should get it ;)


Ridable Animals:

Raptor Elk
Razorfire Boar
Hextadon
Laser Panther
Guillotar
Reaper Steed
Tollusk
(dont remember name, but the bigest animal in the first area, with metal heads)

This acheivment can be quite easy as long as you have got a good memory the acheivment says ride every rideable animal in the game, but it dosent say that you have to ride the animal in single player which you have to do now hear is the list of animals and where to get them

Raptor elk-Starting area
Tollusk-Starter area
Razorfire boar-The temple were you get the guns for the razor girls during the campain.
Guillator-Swampy area
Hextadon-Snowy area
