With only four attacks at its disposal and a Reload move that fills up the Power meter, there's not a lot to expect from this character. It uses the model from Half-Life: Source for its sprites, which are animated surprisingly well, though the character itself is a bit strange, functioning at its fullest during only the first round.
Grunt is a four-button character with a button layout not seen in traditional fighting games, where (X) is a kick, (Y) fires an M4A1 that uses Power, (Z) maxes out the Power meter and (B) throws a grenade. Outside of (X), Grunt quite a powerful character that doesn't really care whether the opponent blocks its attacks or not, given how small the difference between guarded and non-guarded damage is for (Y) and (B).
Grunt's play style is a quite unconventional, having limited uses for all of its moves except (X); (Y) relies on Power, which can either be built-up by using (X) to attack or by using (Z) which fills up the meter entirely, though (Z) can only be used four times and prevents usage of (Y) after the fourth use. (B) is limited to three uses.
