The rough and tumble nature of the Marines was done better in that game than either of the previous two.
I preferred both Alien Campaigns from the first two games over 2010s, think they did better with the lore for the Marines in 2010 (as that is what Jarheads are really like) but still prefer both of the first two games Marine campaigns, and felt the Pred campaign was equal to the first two.
It had his moments, but it did feel unfinished, and the fact we didn't really get any kind of expansions to fill it out was kind of disappointing. Especially since it wasn't uncommon for that era to still do that.
