Graphics and sound are very good. What Halo raises about the mass of the other shooters, in my opinion: - One is forced to tactical as in other FPS (First Person Shooter) to act, because you have to be limited to a main weapon. In addition, completed opponents or fallen comrades must be searched on ammunition reserves / better weapons. - Due to be re-loaded protective suit to fight a certain way in increasing and again flagging waves because you sometimes can make a "Rush" with a fully charged shield (a charge on several opponents without great coverage). Without the armor must we behave once more defensive. - The missions can be mastered with different solutions (I kill the enemy at long range or I sneak on) - The great multiplayer mode also increases still the "long-term benefits" of the game. Conclusion: you!
