MFC based.
	Heavy use of C++ features Encapsulation Inheritance Dynamic binding Exceptions Polymorphism
	Uses DirectPlay IDirectPlay2 interface - multiplayer communication infrastructure.
	Uses DirectSound IDirectSound Interface - smooth mixing of sound effects.
	Multithreaded Main UI thread Game manager worker thread Comm. manager worker thread
	Uses DIBs and the DrawDIB API (from WFW) for animations.
	The Game Manager Main game loop Manages list of objects
	The Comm Manager Communication protocol Synchronization. Message packing and unpacking
	A timer mechanism - time synchronization using smoothed averages.
	Automatic and random map generation Accepts a seed and difficulty level and creates a random map All the machines see the same map No closed (unreachable by tank) areas
	Image manager Lists of images Animations (frame rates, cycles etc) Transparency Collision detection Overlayed images Image offsets.
	Smart queues for inter-thread messaging support.
	Bit-field packing of network messages for optimum bandwidth usage.
	Keyboard manager - Mapping virtual keys into maneuver sets of local tanks.
	Animated user interface Dialog buttons Animation controls

	Bit-wise packing of all messages for smaller packet size.
	Using byte alignment for network packages while maintaining double-word alignment for internal messages.
	Sending compact check-sums periodically (from clients to host) and receiving updates (from host to clients) only when a mismatch passes a variable threshold - preserving bandwidth.
	Each tank sends its maneuver over the network only when it changes (e.g. when a tank moves in a straight line, only two messages are sent - when it starts moving and when it stops moving).

Rendering optimization

	Using double-buffering for smooth animation, preventing flickering.
	Every frame, only the smallest rectangle that contains the objects that changed their appearance since the last frame, is drawn to the screen.
	Using the DrawDIB library bypasses the GDI, resulting in better screen hardware access.

Memory optimization

All messages (internal and network) have the same structure size. We use pool-allocation management techniques to minimize heap calls (malloc / free) and prevent fragmentation.
