You can enjoy the Memento Mori chapter now
The fifth offering of Halo 4's Spartan Ops program is out today, so boot up your game's Infinity menu and select it at will. If you're wondering what the episode is about, it involves secrets and betrayal (like any standard Spartan Operation):
"Secrets are revealed, trusts betrayed and the Sangheili leader Jul 'Mdama's ultimate plan nears success. As Infinity's command crew makes a discovery that changes everything we thought we knew about the Forerunner Prometheans, the Spartans must attempt to rescue one of their own."
Well, we're halfway done with the first (and right now, solely announced) season of Spartan Ops -- what do you think?
I haven't had the chance to crack into Episode 5 yet, but as always, I'm enjoying these episodes with friends.
