Firefight in ODST gives players a chance to actually strategize against groups of AI in a fight for survival. After a few years of being released, I imagine a different branches and kinds of strategies have emerged from dedicated players, and it would be interesting to see how they stack up with and against each other. For example: Last Minute Weaponry When the last 5 enemies are shown, kill the strongest ones and leave the weakest, preferably a grunt. Go through all the weapon spawns and take them from their spawn, especially turrets. That way when reinforcements come, you keep last rounds weaponry AND the new rounds new weapons. I commonly use this in large teams of 4.
