Perhaps you would like the "Long War" mod for the new XCOM (and spencerflem is correct about the dash if that matters). Still one map, but it adds:

- Base defence.

- Larger squads of people who take more time to advance.

- Bit more realistic Panic progression (and satellites / interceptor outpost bring it down AND make them less panicky. shit hits the fan if aliens will destroy either or both).

- Soldiers need more time to recuperate, even without injuries they need a few days off the combat roster (which means that you should have at least thirty people to avoid late-game fight with infirmary patients :D)

More detailed info (here is an archive.org version as UFOpaedia seems to fuck-up recently)

Bonus :D.
