They should add two attacks to Freeza, that whip or slash like attack when he almost cut the planet in half. Goku just dodged that attack in time and that Explosive Ball attack, that Freeza used on Goku. If they use in the game, the ball attack can be blocked or be blasted away by a beam or other attack. If it hits the target, the player who fired may either make the ball explode or kick the ball away and if the ball hits terrain it will explode or explode in mid-air...... .
As for the slash attack or whatever it is, the attack must be charged like a beam and can be thrown at the enemy. It will cause no explosion but it will cause 1/4 damage to the enemy depending on what PL the enemy has.
And correct me if I'm wrong, but Freeza "does" have a beam attack in the series. But he hardly used it in the next episodes.
