Life's a game. How do you play?
Not only the weapons, but the damn soldiers themselves. From driving off of cliffs to fragging themselves and fellow troopers to missing with the goddamn air defense cannon at two meters, soldiers of the UNSC (and, to a lesser degree, the Covenant) somehow managed to make the most so-called "elite force" of the future look like a bunch of boy scouts with paintball guns and water balloons - if the scouts in question had severe cranial trauma. Seriously, I have seen six-year olds with better capabilities than these so-called marines. Grunts are explained by their names, but I expect better of special forces and even SPARTANs, goddamnit! If this is what the future is going to be like, I'm warping through the next slipstream to Warhammer 40k and grabbing the real Space Marines, who are professional enough to know which way the grenade is supposed to go and also that you're supposed to shoot the enemy with your guns, not just wildly blindfire.
