Cross-Platform Play is a Must, as well as Solo Play mode.
We all have friends... We don't control the life choices of those friends.. Some of those friends are PC's, Some are Xboxer, and some are PS4. We should not be required to abandon our current friends and teams just because you don't want to bother with cross-platform play. When my friends come online.. I stop playing Aphex and go to something I can enjoy with them. Cross-Platform play is a must.
Also.. Sometimes I like to play solo.. I don't want to have to follow a squad or worry about other players. In Aphex.. I just let them die and don't even attempt to respawn them. As mentioned above.. These people are not my friends, and i'm forced to play with them against my will rather than those who i'd choose to.. So they are left to die out of spite.
Also.. I know it's in the works.. But more playable characters is really needed... Like.. Fast.
