2 players simultaneous

Games that offer a 2 players simultaneous mode can support two players onscreen at the same time. There are several Vectrex games that have this option. With the Vectropolis 500 demo included on the Vectopia cartridge there is even a playable demo that allows four players to play simultaneously. 

There are games where the players play against each other as well as those where the players play cooperatively against the Vectrex KI. Cooperative games usually show seperate scores for each human player so within a coop game players can compete with each other for the highest scoring.
