WARNING (EXTREMELY) LONG POST!!!!
This is what I believe the Unreal 4 Engine could do....
Just imagine.... Bloaters and Stalkers coming from the western hallway and Husks from the North, after escaping their fiery blasts you turn the corner and see several sirens heading your way, screaming their bloody lungs out while rubble is falling from the ceilings and walls and lights failing. You run through a door and weld it behind you, as you turn around a fleshpound crashes through the wall sending steel shards and drywall flying towards you as you duck to avoid them, the shards become embedded into the counter. you peek over the counter top to see the fleshpound tear one of your buddies to pieces splattering his remains all over the room, then turns and comes crashing towards you. You roll out of harm's way just in time as one of his club-fists swings downwards toward your skull. Annihilating the counters and everything around he turns his face towards you and his blood-foam encrusted lips open to reveal dozens of razor-like teeth as he leaps towards you, but you were ready and with a quick dodge to the right, you fire your dual .50 cal. hand-cannons at his skull, watching in horror as the bullets bounce off of his steel mask, causing bullets to ricochet and rip through anything in their path including yours and your comrade's armor. As you buddy tries to hold the giant off the door you just welded earlier explodes and hundreds of clots come trawling through any openings they can get through. One of the windows breaks from another one of your comrade's failed barrage of bullets, his face pales as he reaches the end of his clip, you make a motion towards the window and he follows, he plants some C4 while running and jumps, on your own jump out you turn and detonate the charge, a huge fireball engulfs the screen as you're thrown out of the building 3 stories up. you luckily land in a carcass filled dumpster, while your buddy wasn't so lucky. You help him to his feet and give him a shot of adrenaline. You both slowly make your way down the alleyway towards your extraction point, only half a block away. Jumping at every sound, every scuttle makes you flinch. When you let down your guard to contact the extraction chopper you hear a noise and watched eyes gaping as you see your comrade dragged screaming up a wall by crawlers, then suddenly there's hundreds more flooding the alleyway, realizing trying to free your comrade would be suicide, you run for the extraction grounds leaving your comrade screaming your name as he's slowly dismembered. As you reach the extraction grounds everything seems eerily quiet, no sounds, no wind, just the ever increasing sound of the chopper approaching the children's park. As the chopper nears, you hear a whizzing sound and half a second later the helicopter explodes into a spinning fireball that overpasses you and crashes towards the Earth. Through the flaming wreckage you see a dark silhouette that cries "I will make you pay for what you have done to my children" just then a whirring sound occurs and you realize that you're being fired at. You run for cover as explosions whirl around you and dive behind a rock not a split-second before the ground explodes behind you in a deafening rumble. As you get to your feet, you see him... The Patriarch... The very cause of this madness, his bloodshot eyes sending a shrill feeling of pure hatred and anger. You raise your bullpup and let him have it with 30 rounds of 5.7x23 mm lead, but with inhuman speed he moves out of harm's way and with a single bound covers 30 yards and slashes at you barely missing your neck by half an inch. You throw yourself away from this monster losing your weapon, drawing your knife and waiting for the last stand to come as you pick yourself up. The Patriarch walks towards you and you run at him, slashing and yelling, he avoids you effortlessly as he grabs your neck and picks you up 4 feet off of the ground, he snarls in your face and pulls back to make the ending move, you struggle to get your hand free, then you hear a sudden *ping as a pin to a grenade was pulled, you smile as you quickly shove the grenade into the creature's broken eye socket, the Patriarch screams in agony as he releases you. You choke and gasp for air as you run away from the blast zone. You are thrown off of your feet and slammed into a rock. After what seems like ages, you manage to stand up and stumble towards the smoldering crater you find no body in it's place. You hear a sound from behind you but you're too late to react as red hot streaks of pain emit from your chest and torso. You look down, dumbfounded as you see a claw stricken through your body, lifted up off of the ground and turned, your vision starts to flicker, and the last thing you see before you drift off into the void is the Patriarch's blood smitten and imploded face staring at you and laughing maniacally...... You then think to yourself "This isn't war... This is hell"..........
What do you think of that? A game like that would totally rock right?
