Metal Gear Solid: Portable Ops Easter Egg - Metal Gear Ac!d reference

1.) Place spies at the Guest House and ensure all other reports from the Guest House have been completed.
2.) Advance time until December 16th 1971, you will get a report about a woman in strange clothing at the Guest House.
3.) Go to the Guest House with a soldier with at least a B in CQC and go to the furthest building to the north.
4.) Go inside and get to the top floor. Inside one of the rooms you will find Teliko (the woman the report mentioned). Get her into a chokehold and press L to interrogate her.

Following these directions she will say one of two things when interrogated, one of which is "See you in MGA". This is a reference to Metal Gear Ac!d (MGA for short), the non-canon Metal Gear game that she appeared in as one of the main characters.
