Cant recall if you can save in SS1 co-op, but I know SS2 had a quick-save/load feature, wasnt any need for a real save feature in SS2 as you can start off at any level you've beaten/are on with your current profile.
(map lengths aint very long, but there's still a crapload of monsters to kill in each one, just not at once)
I quite like the "hoarde" concept of FPSs as well, it was why I fell in love with Painkiller after I got past the shoddy first chapter of it (didn't like the level themes)....huge areas, great graphics, and craaaaaploads of monsters at once, was a major shame it didn't have co-op.
