Sirian Werebulls will kick up dust in the desert masking the approach of the myriads of other enemies chasing you. Juvenile and Adult Arachnoids have great detail and a slight shine to their scales. Characters have been given the overhaul they needed. It's also easy to see the benefits of the new graphics engine by looking at screen shots. It really shows that Croteam's lightheartedness hasn't changed. Selecting "Kids" switches it over to stars and lollipops. A hippie massacre will leave behind new flower beds instead of floors painted red. However, try "Hippie" for a change to make flowers and pumpkins pop out instead of blood and gore. Choosing the standard red allows for exaggerated explosive enemies. Take some time and enjoy playing around with the Blood option, which gives you five choices. Wrapping up the game by battling Ugh-Zan III is one of the most memorable "big boss" battles you'll tackle, while simultaneously being a demonstration of what Serious Engine 3 can deliver. Throw extreme firepower at them and watch chunks of innards fly every where. It allows unmatched frenetic action with what seems like hundreds of enemies on screen at once. High draw distances provide for outdoor levels on a massive scale. Much love was put into the Serious Engine 3 and it displays great potential for upcoming releases. Which leads to the question: is there enough of a reason to revisit the series? Certainly! Every object and texture has been visually invigorated for display in the Serious Engine 3.
