MORE OLD LEVELS. This one comes from Alan Page who also did 'Jailbird 2' and some other good maps. 'Sewage' is a sewer system with tons of button puzzles, underwater areas, lower/rise water effects etc. Design is good and detailed as are shadows too. Puzzles are above average - I was a bit lost couple of times (actually that was more likely because of my own stupidity). Good enemy/weapon balance and gameplay (but there's one annoying jump scene). In the end Duke gets out of the sewers and destroys some buildings (good effects) and founds Canadian Parliament Building (looks very good).
