200 plus AI on screen - Halo Reach

[iWarMachine]

"In what looks like the "dumbest" comparison, EGM have decided to side by side compare Halo 3 - due out on release in under 3 weeks, with the alpha build of Sony's KillZone 2 that was previewed at E3. Despite the game being almost a year away from completion, and despite the developers noting that the A.I was not yet complete, the journalists at EGM wanted to include the game in their "Best Of.." section of the magazine and it seemed like the only category best suited for KillZone 2 was the "Dumbest AI"."

idiot comparison is idiot...

KILLZONE 2 : Best AI in a AAA Game

The combat AI that Guerrilla Games built over the past 7-8 years since Shellshock: Nam '67, including Killzone 1 for the PS2 and Killzone: Liberation for the PSP has arguably become the best in industry with this latest iteration. The enemy behaviors are dynamic and adaptive, showing off both linear sections and large open areas of the game thanks to its tactical reasoning.

The AI in KILLZONE 2 in particular shines in the Skirmish mode where you can play with computer-controlled bots in large open maps designed for multiplayer, and free of scripts and trigger boxes. The bots were intended for offline play where you have 7 bots on your side against 8 enemies, but you can also compete online with your friends against various combinations of bots. Not only were the bots fun to play against, according many reviewers including to Ryan O'Donnell of Area5.TV, but they even passed an informal Turing test with journalists from the CO-OP show (season 2, episode 1) and others:

“The bot thing is pretty amazing. I was telling you earlier that I was playing it and it was behaving in such a particularly clever way in this one area that I had to check that I wasn't play online.”
— John Davison, WhatTheyPlay.com

Some reviewers even speculated that Skirmish and multiplayer bots were included simply to emphasize the strength of the combat AI. You can watch some High Quality videos of matches against the bots in the Salmun Market or the Radec Academy.

Cooperative buddy AI that accompany you through the game (while actually fighting alongside you) is generally a hard problem that nobody has got entirely right to-date, and there's still room for improvement in Killzone 2's buddies. However, it's one of the best attempts yet and given the underlying engine there's even more potential. In particular, there's a balance to be found between the aggressiveness that can save you in tricky situations vs. buddies playing safe so you don't need to revive them too often.
