Navagon: But personally I didn't feel like going any further with it than that sewer section with the rats.
Oh, you haven't been to the Central American jungle and temple, human outpost in an alien world (including alien Indiana Jones-ish puzzles), hell offices (literally, there's a level of offices with demon mobs and screams of agony playing instead of music)... Admittedly this also means you haven't seen much of the ragdoll, haven't discovered that most enemies die fast to one gun, haven't stumbled into a level with iffy scripting which may get you stuck... fair enough...
Licurg: I read somewhere that it's uncomfortable to play without a gamepad, and that stopped me from getting it in the first place.
There's gamepad support?
I felt, that the game controlled much better than similar Bandits, because none of the cars in HTA have fixed forward-firing guns. Everything is mouse-aimed, like the turrets in Freelancer.
