Archon ---> Quake. You heard right, elements of the 80's micro game archon extrapolated into the Quake universe. Get ready for a wild ride. (free stuff | no warranty | see disclaimer.txt | blah blah blah.)
The "Lava" Scragg - a monster upgrade. Not just a scragg with a lava / cthon skin. He shoots explosive lava balls. And the effect seen here - he has a melee attack. Get too close and he sets everything around him on fire! You can hear a bossman complaining nearby - the Lava Scragg set him on fire during this test.
I must admit though - his frames seem odd...already see what the problem is.
WTF is going on???
This monster has a melee attack when the player gets too close - he starts a shitload of fires. Without something like the HD pack, q1 fires look like that hot puff sprite. Under the HD pack they look more like fire.
So to recap - the "lava" skinned scragg has a melee area flame strike power.
