I bought Halo 4 for single player, finished it, and found it was overall money well spent. Still....You can't help but wonder if they give command posts in cereal boxes in this setting. Let's see, level by level, some brilliant tactical decisions First Level : -Cortana have been watching the channels for 4 years, and apparently missed ''dritfing at subspace speed toward a giant metal planet'' and ''a whole Covenant armada''. How exactly she was monitoring the situation ? -Feliciations to the Covenant commander that have sent several dropships over a dead Human ship, see the troop complement of the dropships being mowed down, and still not consider raising shields Third Level : -Cortana and Chief, have you considered not pushing random buttons on devices you don't understand the purpose ? Especially considering the Flood incidents -The Infinity. I dunno guys, but have you considered that ''sending the super flagship of the UNSC'' through a mysterious hole in a metal planet might not be a very sound plan ? Why not send a probe or a dropshup ? Fourth Level; -I think that it would have been a good idea to use the superpowerful combat mech as the ennemy was invading the ship and not wait for a guy presumed dead for 4 years to come to pilot it Fifth Level : -No wonder the UNSC was trashed into space, considering that their ships apparently require people to manually provide targets for their big guns with hand-operated targeting devices. You would think that it's pretty inconvenient for space warfare. Sixth Level: Granted, Cortana was suffering from brain damage, but how exactly the MC is supposed to attack Didact ''by surprise'' when the plan involve him lowering the shields in two towers ? Seventh Level : No one thought of using those super fighters when the station was invaded ?
