セックス あ～ん♪ パンツァー

The system was perversely limited to use by young girls.

Two candidates were inducted into the system and unleashed on the enemy.

• YOU must press on!
  Deal epic destruction as a bullet-spraying missile-launching
  Japanese girl against overwhelming oddness, revel in the destruction
  in the alternate warscape of future-past 1969!
  press onward into enemy territory dealing swaths of glorious destruction!

• And of COURSE (?)..
  Should you fail there's assault animations to behold!
  Trample into battle with an eye for "winning" AND "losing"
  utilizing the Sex Streak System:

• Chain your attacks to produce a massive super-explosion!
• Get assaulted for a sustained length and power up!

Turn the tables from violation to victory. That's the Sex Stream System's merit!
