Isonzo successfully bridges the worlds of simulator and more traditional shooters to make a legitimately entertaining, yet historically minded first person shooter.
The movement mechanics are a bit slow paced to be perfectly aligned with my tastes, but it does keep ridiculous antics like bunny hopping at bay. The spawning, map design, and flow of battle is fast paced enough to keep the action rolling, rather than becoming tedious like other more simulator games.

Team play and the objective focused flow of battle are the two highlights of the game’s design. Teamwork is critical to success. Each class, and even each perk/loadout takes up some cog in the grand machinery (or chaos jalopy) that is your team.
The best way for you as an individual to swing the tide of battle is not necessarily to one man army the objective (because let's be honest that’s probably not going to happen).
Rather it could be the strategically placed ammo/grenade boxes outside an objective, an expertly timed gas attack, a position fortified with sandbags and barbed wire, or the perfect hidden spot for your squad to spawn on you and get a sneaky flank.

Your WW1 adventure takes place upon a dynamic front line that will move as objectives within a sector are achieved. Some objectives only have to be taken once, such as sabotaging gun emplacements, others have to be held, and can change ownership. In addition to the primary objectives there are secondary emplacements to fight over, that are not technically necessary to take a sector, but can be strategic game changers. For example a defending team could gain a significant advantage by penetrating thru attacker’s lines to sabotage their forward spawn emplacements.

Much like M2H’s previous WW1 titles, Isonzo has a bit of a learning curve.
You will die a lot.
Have patience though, soon things will start to fall into place.
You will still die a lot.
It is WW1 after all.
But you will start to take a lot more guys with you.
You will understand the flow of battle, and play objectives better.
The niches of the classes will make sense, and you will play them to their strengths.
Congratulations, you are now a functioning cog in the great war machine, and so long as it's virtual, it's pretty entertaining.
