5. Once the other player has joined and is ready, click Start.

You may notice a timer in the upper-left corner of the screen. If one 
player's computer is particularly slow, this timer keeps track of the time 
that player has left to join before he is dropped from the game. Once both 
players' computers are synchronized, the game will begin.

3. CREATING AND JOINING MULTIPLAYER GAME SESSIONS
-------------------------------------------------

3.1  Creating a Multiplayer Game Session
----------------------------------------

>>>To create a multiplayer game session

1. Follow the procedure for the type of connection you want to make (see 
the procedures in Section 2 for specific connection types), and then click 
Create Session.
2. On the Level Selection screen, select a level, and then click OK. Be sure 
that the level you select has at least as many factions as the number of 
people playing. (Note that if you are playing over a modem, a serial 
connection, the Internet Gaming Zone, or the Internet, you should select a 
level with a telephone icon next to it. A telephone icon indicates that the 
level has been optimized for low-bandwidth play and will offer the highest 
performance for your type of connection.)
3. On the Start Game screen, select your faction, and then wait for the 
other players to join. (Players cannot play as the same faction.)
4. Once the other player has joined and is ready, click Start.

You may notice a timer in the upper-left corner of the screen. If one 
player's computer is particularly slow, this timer keeps track of the time 
that player has left to join before he is dropped from the game. Once all 
players' computers are synchronized, the game will begin.


3.2  Joining a Multiplayer Game Session
---------------------------------------

>>>To join a multiplayer game session

1. Follow the procedure for the type of connection you want to make (see 
the procedures in Section 2 for specific connection types).
2. On the Create or Join Session screen, select the game you want to join, 
and then click Join.
3. On the Start Game screen, select your faction, and then click I'm Ready! 
(Players cannot play as the same faction.) Once you have clicked I'm Ready!, 
the host can start the game.

You may notice a timer in the upper-left corner of the screen. If one 
player's computer is particularly slow, this timer keeps track of the time 
that player has left to join before he is dropped from the game. Once all 
players' computers are synchronized, the game will begin.

4. UNIT LIMITS
--------------

There are two types of unit limits that you will encounter in multiplayer 
games. One is the "hard" limit type, for low-bandwidth games (these levels 
are indicated by telephone icons on the Level Selection screen), and the 
other is the "soft" limit type, for high-bandwidth games.


Hard Limit

The hard limit is pretty basic. Once you reach the hard limit, you will no 
longer be able to create any additional units until those that have already 
been created are destroyed. The hard limit is used for low-bandwidth levels.


Soft Limit

The soft limit works on the idea that the more units you create the less 
efficient your energy absorption rate becomes (see your printed documentation 
and online Help for information on the Energy Manager and resource management). 
Once you reach the soft limit, every unit you create over the limit causes 
your energy efficiency to drop by 5% (you may not notice this if you have 
already had the good fortune to conquer numerous sectors). The way to return 
your energy efficiency back to 100% is to either conquer more sectors or 
destroy your other units.

---------------------------
5. KNOWN MULTIPLAYER ISSUES
---------------------------

ISSUE: On the Connection Type Selection screen, there is not a connection type 
listed for the Microsoft Internet Gaming Zone.

Suggestion: Connect to the Internet Gaming Zone first and enter the Urban 
Assault Lobby. Once all the players are in the correct room, have the host 
click Launch Urban Assault from the Zone Lobby.

ISSUE: The Microsoft Internet Gaming Zone may not automatically start Urban 
Assault for some players.

Suggestion: Be sure that players do not have Urban Assault running when the 
host tries to start a game from the Zone.

ISSUE: If the host exits a game before a player has joined and the host then 
rejoins as a client, there will be no way to start the game, as both computers 
will be clients and the Start button will not be available to any player.

Suggestion: The host should exit from the Start Game screen and then create a 
new multiplayer game. Once it has been created and the level has been selected, 
the client can then join.

ISSUE: If you receive the message "System Error: [Opponent] has files that are 
different from yours," one or more files in your Urban Assault folder vary 
from those of your opponent. This can happen if files are edited or deleted 
from the Urban Assault folder on either computer. This message is in place to 
ensure that all players have the same files and to prevent cheating with edited 
files.

Suggestion: When this message appears, all players should uninstall and then 
reinstall Urban Assault. Not doing so may prevent Urban Assault from running 
or may give one player a distinct advantage over other players.

ISSUE: Higher resolutions my cause latency problems.

Suggestion: Reduce your resolution in the Display Resolution box on the 
Options screen.

ISSUE: When Dial-Up Networking times out, the game may crash if you click 
Reconnect in the Reestablish Connection dialog box while it attempts to retry 
your connection.

Suggestion: Always exit Urban Assault before you attempt to retry a Dial-Up 
Networking connection.

ISSUE: After a multiplayer game session, internal modems may stay on after the 
game has ended.

Suggestion: Restart your computer to turn off the modem.

6. MISCELLANEOUS
----------------

** Enemy AI is not available in multiplayer games.

** A single player can create and play a multiplayer game. This is an excellent 
way to try out enemy vehicles and check out the terrain of the various 
multiplayer levels before you take on an actual enemy.

** On the Create or Join Session screen, levels with a telephone icon next to 
them are for low-bandwidth connections (Internet TCP/IP, Internet Gaming 
Zone, Modem, or Serial connections). Playing other levels with these types of 
connections will most likely result in poor gameplay performance and is not 
recommended.

** Pressing ALT+TAB may cause a loss of network connections to other players. 
Do not press ALT+TAB while playing multiplayer games.
