I've felt strongly compelled to try and rescue this title from some undeserved criticism.
When I see something developers are doing right I like to try and encourage what they did right before cries of what they've done wrong inevitably toss the baby out with the bath water.
Let's get out of the way what is wrong with Burn Zombie! Burn! first.
Simply put the point goals have been set way too damn high and even the best of players have gone over ten minutes of enduring one level just to achieve a Silver.
Also, per Vyrastas extremely informative point scoring walkthrough http://au.ign.com/faqs/2011/burn-zombie-burn-walkthrough-1081706
He mentions that the R1 button feature has been removed from the Steam release. Holding down the shoulder button allowed for manual aiming apparently using one of the analogues'
From YouTube playthroughs I have also noticed the Lawnmower weapon turning up more frequently in the native PS3 version and it is that Lawnmower + Zombies on Fire which scores and drops dynamite upgrades the quickest.
But despite the painstaking goal ahead of Steam gamers, Burn Zombie applies good old fashioned thumb-active game play and this is to be as heavily pointed out as it is commended.
On release there were many cries for twin stick shooting (unfortunately offered in sequels) thus ignoring that such unsophisticated controls not only take away much of the challenge but also removes the feature of each weapon having it's own unique manner of use: ie; rapid pressing of the fire button while holding the pistol offers quick but weak bursts while shorter and harder presses release less bullets but those shots do more damage.
In this wave shooter the number of zombies released at one time is perfectly balanced. The controls (despite missing the R1 option) are enjoyable for those who love getting thumb exercise on game pads and it is this alone that makes BZB worth purchase.
However the value should be taken into consideration before purchasing. With the flaws mentioned above I wouldn't suggest spending over $5 for this title and only recommend the game to those gamers who don't mind exhaustive thirty minute runs to try and accomplish only one goal.
