This needs a sequel very much,to be designed mainly by 2 people this is one of the ,most amazing free games that i can find on this genre.This game could use a few things to make it much better.One new units,the reason is obvious and everybody wants it.Two maybe a multiplayer,like this game is one of them that are made to be a good multiplayer,also make it where the multiplare doesn't affect the main game AT ALL please make it just for fun.Three custom mode?Like design enemy waves,challenges,levels,and even maybe a custom campaign maker?I don't know but these things would make for an AMAZING sequel.But thats just my opinion
You know what Nitrome would make a new better version of this with more levels and a tank editor that so many people would love,but no that would take too much work so they probably won't I hope they do make a sequel but until then I started losing interest in this game and Nitrome as a whole.
