Well, the trophies should be quicker
Having to kill 300 everything is dumb.
The harder the enemy is the less should be required
However, I noticed that there is a way to summon the desirable monsters.
To summon lickers / shitters / vomiters, just stay where you are, and they should appear
If you want Iluheads, you have to move a little beyond your car visibility, etc.
I'm speaking about "defend the car" route, which is the most frequent shit to happen
during gameplay. Experiment on your own, for the results you need, but the only problem are the last 6 / 8 types of villains to complete. It's weird that so far only one person had balls to grind it.
The game is good, but I do want to punch your guts for such requirements.
