You can all ways play co-op by yourself and try to hide one of the players or at least keep him out of as much trouble as possible
There's no way id've managed it single player only.
I hope they make a sequel and enable online co-op.
That's just not on
But yeah it can get a bit rough... I do hope they do a sesqyel with online, 4 players would be even better for total madness!
I tend to stick to the rocket launcher and assault rifle type weapons but would lie any other recommendations, cheers.
Post 48 page 4, also see posts 61 and 67 (68?).
The assault rifles are a bit of personal preference. AF100 is all-around best IMO though, however there is an AF99 which has really long range (420m?) which is good as you can hit UFOs and not need another weapon and means you can take a turret. Ammo capacity; there's a 999 ammo AF99 and fires 60(?) per second.
The laser guns you see troops using are a reward for finishing one of the difficulty levels, easy i think? it's called the Zero laser Rifle, but isnt that good because like a lot of energy weapons you cant recharge them.
Certain weapons are situational; i quite like the "Bound" guns for tunnel levels or flamethrowers/Magma Cannon, ditto the "Brute J Triple" grenade launcher and the "Stampede" vs the big bosses. Dont ignore the sniper rifles either, as you level up they are often better than the rocket launchers or rifles.
The shotguns and missile launchers are generally a bit poor compared to the PS2 games, plus an almost complete lack of energy weapons. I hope they continue the series from The Chikyuu Boueguin 2 rather than EDF 2017.
One of course cant go without mentioning the Genocide Gun <Dr Evil voice> one million damage! /<Dr Evil voice>
but you get it for finishing Inferno, so probably wont see much use sadly. Just have fun experimenting with the guns you unlock, as thats the point of the game really.
