Oh and another thing, SAS 3 has WAY better game modes as well. Onslaught and Purge, while on paper much less detailed than the various missions in SAS 4, invoke more interesting actual gameplay. Sure the missions in 4 can sound very different from each other based on what you do, but the gameplay is mostly the same; traverse the map and kill all the zombies you find and reach certain points on the map without dying. That is essentially what you do on most missions. A big problem with this is that it's usually too easy. All you have to do is go into a new area and kill some zombies, usually able to retreat to earlier portions of the map that are clear of zombies. But in SAS 3 it's more about frantically killing the zombies as they spawn in greater and greater numbers to avoid being overrun. SAS 4 is really a great game but there just are some things about it that frustrate me, that's all.
