IG-88 Gear/Senses

He  halted  three  meters  from  the  scabbed  surface  of  the  armor-plated  doorway  and  launched  his  first  con­ cussion  grenade.  He  calculated that  even from  here the  shockwave wouldn't damage him.   The  detonation  struck  the  center  of  the  door  and  reverberated  like  an  immense  gong  up  and  down  the  canyon.  Rocks  fell in  a small  avalanche from  the cliff  walls. The  sentries in  the turrets  ineffectively blasted  down  with  their  laser  cannons,  leaving  only  scorched  trails, but missing the droid.

Using  various  spectral filters,  IG-88 scanned  the dam­aged  door.  The  center  blazed  in  infrared as  the heat  dissipated.  He  analyzed  the  vibrational  signature  and  noted  where  the  structure  of  the  metal  now  showed  fine crystalline cracks. Satisfied, he prepared a second concussion grenade.

IG-88 had  twelve  in  his  store,  and  he  expected this  door would require only three.

Actually,  it  took  four  grenades to  completely destroy  the  door.  As  the  smoldering  molten  wreckage  of  the  doorway  crashed  to  either side,  IG-88 clomped  into the  fortress,  determined  to recalibrate  his sensors  and his  predictive models when he had the time.
