\begin{itemize}

	\item \textbf{Campaign}: campaign mode; kill all autonomous opponents.

	\item \textbf{Zombies}: zombies mode; kill as many zombies and survive as much time as possible.

	\item \textbf{Back}: go back to main menu.

\end{itemize}

The user can also go back to main menu by pressing \textbf{ESC}.

Configuration of the UART was made using the functions \texttt{graph\_init} and \texttt{graph\_cleanup} developed during the project. Drawing to the buffer is made primarily through the functions \texttt{graph\_get\_XRes}, \linebreak \texttt{graph\_get\_YRes}, \texttt{graph\_set\_pixel}, \texttt{graph\_clear\_screen} and \texttt{graph\_draw}.\par

Basic sprites are constructed from small XPM files, or loaded at runtime from XPM2 files. A XPM2 file is a XPM file stripped from all the C syntax, leaving only the strings. This format is easier to load at runtime than XPM. A XPM file can be easily converted to a XPM2 file using the function \texttt{xpm\_save\_as\_xpm2}. All XPM arrays of strings are loaded to bitmaps using the function \texttt{xpm\_load} provided by the LCF.

\subsection{Serial port}

The UART was configured to issue interrupts for Receiver Ready and Transmitter Empty. Communication is processed with the same parameters at both ends, at a bit-rate of 115200bps, 8 bits per char, 2 stop bits. UART FIFOs are not used. The protocols that were developed will be discussed in section \ref{sec:details}. \par

In multiplayer mode, data is transferred from host to remote at a frequency of 60Hz, with each message having at least 24 bytes. Data transference from remote to host is made whenever needed, with each message having on average 9 bytes.
