Since this is a free to play browser game it wouldn't hurt to make a cp to gp conversion thingy , like 1000 cr to 1 gp , and you should make the single player campaign only in the offline version , the multiplayer version should stay in the browser forever cheers :)
if enough work is done on it , and better weapons , HUD and menu and xp and money system is added and much stable web haster and graphics is updated this game could be our next red crucible 2/uberstrike or might even reach the greatness of contract wars and ballistic
