Tanks ‘n Planes Unlimited (TPU) is a dedicated co-op Battlefield 1942 game server. It is open for anyone to join. All you need to play is a Battlefield 1942 game client. To play all the maps in the regular rotation, you will need both of the official add-ons: The Road To Rome and Secret Weapons. The Battlefield 1942 client and the two add-ons can be downloaded via the Files page on this site. There’s an excellent guide to setting up Battlefield 1942 on modern Windows PCs in the Battlefield subreddit on Reddit.
Although most of the maps have been modified to some extent, we have tried to make sure that no special downloads are required for joining the server. Modifications have mostly been limited to increasing the number of tank and plane spawns and swapping certain units for others (one type of plane or tank for another). More recent mods involve adding gun emplacements, moving ships around and adding subs.
TPU runs 24/7, with all of the standard (but modded) maps in the rotation, 32 total players and an Axis:Allied ratio of 3:1 for six hours, switching to a 3:1 Allied:Axis ratio for six hours after that, and so on. Make sure you always join or switch to the side with fewer total players. You will fight with a small team of humans and bots against a much larger team of all bots.
