okay, i have games halo and halo 2, unluckily dont have 360 for halo 3 or odst or wars. Ive currently played more halo than halo 2 since its a bit longer and im stuck in halo 2, im stuck because im used to holding one gun at a time and used to holding guns that dont mvoe while u shoot! this makes halo 2 three times as hard for me. im up to almost the end but i think its the last part of the flood. when the sentinels (or manateees in halo 1) and the flood both chase you, they attack themselves but since there is nowhere to hide they all see you as the greter enemy, they all go charging for u, u scrooed. especially when used to holding 1 gun. i try throw a grenade and shoot accidently with otehr gun. -.- i think it is easier with 1 gun. or at least if its 2 guns, both always have same ammo, fire at same time and are both controlled by one button. R trigger that is.
