Oblivion Lost Q&A

Rat swarms moving through the grass...yummy.
From the STALKER info pages on www.gsc-game.com :
Rats
After the catastrophe many animals died and left the Zone, many, but not the rats. They bred in great numbers to become the top numerous Zone animals. Rats are found in groups, and rarely individually.

Apart from usual rats you may find rat wolves, who are bigger and more aggressive. Rat wolves devour their kin in famine.

Rats feel dangerous areas and carefully avoid them, squeaking to warn the rest of rats. Rats are very witty creatures and try circling their victims around. A victim, surrounded from all sides stands no chance to survive.

Movement: Rats move by jumping onto and going through any accessible passageways, holes, cracks and windows. Rats try to stay in ill-lit areas and avoid anomalous zones.
Enemy search: Rats have poor sight and therefore tend to sniff and listen more. A group follows the general mass of rats. If a prey got lost, rats disperse around the presumed area of prey hideout.
Escaping from under fire: Rats avoid fire. They run to where fire is initiated from.
Assault: They jump on victim, so that it gets covered with masses of rats. Rat wolves aim to jump on victim's back.
Battlefield fleeing: If a group of rats got defeated and failed to cover a victim within 30 seconds, it disperses, then gathers into several large squads to attack again. If there is 20% of rat group remaining, rats flee the battlefield, scattering in different directions through any passageways and cracks.
Hiding:Rats try to stay in shadowy areas.
Enemy outflanking: A group splits into several large squads, which attack from different sides.
Tricks: Rats fall down from holes in ceiling and jump through windows.
Weak spot: Rats are good to burn.

Where rat encounters are possible:
In basements, cesspools, building debris.

60 fps are easily attained even on average computer configuration.

So what's average?
