I did notice a few bits done in ODST and other areas of the past games but they folded really well into the story it was pretty dam awesome.
And there are times i felt impossible to stop. City mission protecting the elevator from the brutes is one example.
I felt like reach was trying to show how much it could do in firefight like stand offs like in ODST but then carried on with the same mission was un-expected and i great touch.
Unable to fight a scarab however was a lil lame and the surprise of Drones appearing was unwelcome due to me having no weapons that could effectively counter them.
Over all 9/10 great campaign
And the ending i saw before the game came out so i knew what to expect i liked it though id carry on but the spoilers will be heavy no matter how i slice it
Aloysius:If you think about it, Galactus is a giant purple alien who eats planets. Kind of like the Covenant.
It's official, straight from the mouth of an employee who works on Halo.
The Covenant eat planets.
