Thanks for playing! According to your feedback, the following changes has been made in this version.

Zone Transition_3: The 2 charger scouts in Area A has been replaced by a tank.
Some non-thermal gears are un-banned.
ZONE_902, [RAGNAROK] MAINTENANCE CORE, ZONE_908:
- Significantly reduced amount of medi, ammo packs
- Added Ammunition Station, Health Station
[RAGNAROK] MAINTENANCE CORE zone scan: intensified 3-staged waves a bit, more exactly:
- 1-stage pre-, post-1st-tank wave; the 2nd tank now spawns later as well;
- 2-stage post-pmother wave;
- 3-stage immortal tank wave.
[RAGNAROK] self-destruction alarm in ZONE_900:
- Self-destruction SFX effect now plays after alarm being completed, to prevent camera shaking effect interfering player aim.
- All security sensors would be disabled after alarm being completed.
- Wave intensified a bit:
  - Now wave enemy spawns from all sides instead of only from 1 side.
  - However, hybrid and big charger would always spawn only from 1 side.
  - Last scan of the alarm has been changed from a concurrent-duo S scan to a single S scan at the center of the zone.
- Extraction is made more unreasonable
  - However, expedition will still be successful, as long as the self-destruction alarm has been completed.
