Destiny is a relatively new game which has received wide spread acclaim. It is definitely worth checking out.
This game has been created by the creators of Halo and Call of Duty, which is certainly a brand which has earned respect amongst gamers the world over.
Within the game, you play in a dystopian future where much of the human race and civilisation has fallen to ruins, with you playing a guardian of the humans’ last city. You can explore all of the ancient ruins, in your choice of game-style, with single player and cooperative versions.
The enemy, much like in Halo, is an aggressive alien race bent on the destruction of humans. You play a guardian of the last human city, where you try to fight back the hordes. You can travel from planet to planet and see all of the battlefronts taking place against the enemy.
