Both of these help to extend the life of the game quite decently. Network Gaming or How to Annoy your Boss in One Easy Step Support for multiplayer games comes in two flavours, 2-3 players on one machine or IPX network gaming. Only the Arena game type is multplayer-capable. There are also the usual deathmatch or co-operative games. In deathmatch, there are a few different ways of ending a game, either by frag limit, time limit, lives or difference.
Difference means that if a player gets a particular number of kills ahead, they automatically win.
The game is played in a split screen view if using just the one keyboard. The downside to this, in case you hadn't already guessed, is that it makes the screen rather cramped, meaning you almost have to have a big monitor in a high resolution to play it. IPX games are played in a similar fashion, except without the split screen. On the whole it plays rather smoothly. Well, while the game does have its flaws, it is still pretty enjoyable, and at the end of the day, that's all you're really asking for.
