My opinions on each legendary campaign; Halo CE: Fairly hard. Halo 2: Makes Dark Souls look like a 4 year old's game. Halo 3: Fun Challenge. Halo Wars: I forgot... Halo 3 ODST: almost if not on par with Halo 2's Halo Reach: Same as H3 Halo 4: Lmao, if you think this is hard... wow I really don't know what to say. (Barely a Halo game) Halo 5: ... What? this is a HALO game thread not Call of Duty advanced Halo-fare.
