The applet version doesn't have the [ALT]-(s, y, x, c) steering! Use the key d to enter and leave the shooting mode! This is necessary, because the browsers' menu could be activated with ALT-commands.

You need a JAVA Browser to use this applet!
If you can't make it run and really want to play, you can use the AppletViewer from the Oracle JDK and start it with the .htm file as argument.

Dynamite Guns 3D For Two is a version of the Astro Solutions game Dynamite, where you don't place bombs on the gameboard, but throw the bombs after the enemies. You can choose one of eleven levels and have to eliminate all enemies. This is a version for two players. The first player uses the arrow keys. If he presses shift while choosing a direction, he shoots. Otherwise he walks. The second player uses the keys s, y, x, and c to walk or shoot. The mode is entered or left with the key d. The first player enables the camera position change mode, if he presses the key -, and leaves the mode with pressing - again. The second player uses the key a to enter and leave the camera positioning mode.

This game is thread-safe. The applet is compatible to JAVA 1.1.8, MSJVM and JAVA 1.8 and uses a deprecated JAVA API.
