Arkose: Make no mistake:
this is the Big Rigs of zombie games. An unbelievably low-budget game (even by budget game standards) launched while apparently still in the alpha stage. Even the much-derided Superman 64 was actually
finished; this isn't.
It would be easier for me to count the things this game got
right than what it got wrong. Post-release patches have reportedly fixed some issues but it is still a broken mishmash of average ideas implemented poorly. Top this all off with zero performance optimisation (crawling frame rates on good systems despite sporting 2002 graphics quality) and you have the best $10 you ever flushed down the toilet. This was somewhat acceptable in 2002, but with the likes of GOG selling top-quality older titles for $10 or less not even their "indie" status can let them get away with selling game this terrible.
If you closed your eyes and picked a game on GOG completely at random you'd be guaranteed to end up with something vastly more enjoyable
for the same price or less, even if it's a genre or game style you don't even like.
EDIT: if you want a fuller indication of what the game holds,
read this review. He highlights most of the many flaws this game has.
