How come I am not seeing all 2nd wave options?

The first four are available for the first playthrough:
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

The following ones can be activated once the game is won on Normal, Classic or Impossible:
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

The last four options are only available after winning on Impossible:
Total Loss- Lose all soldier gear upon death
War Weariness- Funding goes down over time
E-115- Elerium degrades over time
Alternate Sources- The power source cost to build facilities increases dramatically

Got these from this topic:
