If XCOM already has you bent over a barrel, you might want to pass up on today's free DLC offering, Second Wave. The download unlocks a bunch of game options designed to punish sloppy generalship, where "sloppy" stands for "not quite comparable to the achievements of Tacitus and Sun Tzu". For instance: council funding dropping over time, and soldiers losing all their gear when they die. Ouch.
Four of the new options unlock once you complete the campaign on Impossible. There they are below, care of CVG.
Damage Roulette: Weapons have a wider range of damage.*
New Economy: Randomized council member funding.*
Not Created Equally: Rookies will have random starting stats.*
Hidden Potential: As a soldier is promoted, stats increase randomly.*
Red Fog: Combat wounds will degrade the soldier's mission stats.
Absolutely Critical: A flanking shot guarantees a critical hit.
The Greater Good: Psionics can only be learned from interrogating a psionic alien.
Marathon: The game takes considerably longer to complete.
Results Driven: A country offers less funding as its panic level increases.
High Stakes: Random rewards for stopping alien abductions.
Diminishing Returns: Increased cost of satellite construction.
More Than Human: The psionic gift is extremely rare.
War Weariness: Funding goes down over time. **
E-115: Elerium degrades over time. **
Total Loss: Lose all soldier gear upon death. **
Alternate Sources: The power source cost to build facilities increases dramatically. **
*Unlocked prior to completion of campaign.
** Obtainable upon completion of Impossible difficulty
