4. Big open levels

Killzone 2 wowed with its realistic portrayal of gritty urban warfare: fighting constrained by city streets, dark alleys and the very homes of the locals. For Killzone 3 we'd love to see bigger levels that allow you to spread your creative wings and flex those little grey cells. We're not talking open world here – other first-person shooters, like Far Cry 2 and Crysis, do an admirable job of that. Nor are we talking about dumping the claustrophobic feel of city warfare Killzone 2 so superbly simulated. We're talking about choice and variation. Instead of entering a new area, finding cover, fighting till everything's dead, then rinsing and repeating, we'd love Killzone 3 to allow us to utilise more than our trigger fingers and unquestioned hand eye coordination when dealing with the enemy. How about scouting enemy positions? How about setting up diversions? How about carefully coordinated flanking and pincer attacks? How about stealth missions? How about spotting a holed up Helghast half a mile away and sniping him in between the eyes? It's all possible, and it would make Killzone 3 even better than Killzone 2.

3. A genuine moral dilemma

The potential is there, hidden underneath Killzone's expletive-ridden dialogue and juvenile machismo, for Guerrilla to make a statement of some intelligence with its universe. Think about it. The Helghast are an enemy of the ISA's own making. They are a people driven to the brink by their harsh surroundings. Their dictator leader might simply have been a man misunderstood, a man trying to do what's best for his people. With the ISA now in tatters and the Helghast still fighting for their lives, Killzone 3 presents an opportunity missed with Killzone 2. How about posing proper moral dilemmas? How about asking the player to make difficult decisions in between headshots? How about forcing the player to answer questions with no obvious right or wrong answers? How about letting the player decide what side he or she fights for? The ISA Helghan conflict is a virtual metaphor for much of the real world's current disputes, but you'd never know it. With Killzone 3, Guerrilla can change that.
