This addon randomly places additional objects in the official campaign.

You play the same official map all the time, don't you want something new every now and then? Wouldn't it be possible to change gaming experience, just by slightly changing the placement of the object?

- Additional objects are selected from among those that match the basic atmosphere of the campaign. - Objects are randomly spawned every round. - Most of the newly deployed vehicles can be hit and dribbled by Tanks. (except buses or military vehicles)

Probably the campaign's Walkthrough route may be changed.

In some campaigns, there are several route in addition to the main ones. But since people prefer fast routes, these side routes are often overlooked. Maybe there are people who have never been there and didn't even know there was such a route?

- In Chapter 1 of No Mercy, the shortest route to the subway station may be blocked. You need to go through the warehouse behind the parking lot. - In Chapter 4 of the Blood Harvest, the warehouse door may be closed. You have to go around the back of the building.

If you don't want the spitter's acid to pass through an objects,

Try use Improved Acid Spread. The game may get a little difficult, but it will be fun. Easy games are no fun!

This addon also works in Versus mode.

Both teams can play a fair match under the same object placement conditions.

Support only official campaigns. No effect on add-on maps.

The campaigns currently supported are as follows.

- No Mercy - Crash Course - Death Toll - Dead Air - Blood Harvest - The Passing - The Sacrifice - Dead Center - Dark Carnival - Swamp Fever - Hard Rain - The Parish - The Last Stand

※ This add-on can be used alone, but it is also great to use with Random Car Alarm Controller. (recommended)

※ This addon conflicts with the addon below.

This addon modifies the "nav mesh" of the map to actively take advantage of obstacles. Because of this, it cannot be used with another addons that also modify nav meshes. - Corrected Nav - NavFixes
