I started playing this game like two months ago … and I played solo mostly, so perhaps they have fixed some of these challenges @malkav11 faced before, I am not sure. The game is exciting and there are some tactical elements to it. If you are being flanked, then use a turret, or pulse the enemy before you start to engage them, so you can double the damage inflicted. Or get to higher ground so you have height advantage.
The better the AI, the more fun solo experience, isn’t it, as compare to some dumb AI which rushed at you? I am perplex to hear people giving up in solo… this game is very playable in solo but it is challenging - not impossible and frustrating - who has time for these type of games anymore.
Perhaps you stumbled into a higher than your current level area? Then stay on the area at your level - the game is too open and you could end up in a “dangerous” area, just pull back like any other single player game and spend time levelling up in the area you are supposed to be in. There’s tons of missions in any area for you to play and get the xp to level up.
Edit to add: yeah, the game does focus on getting the right gear/armor and also the right tech upgrade (of your Base of Operations - think of this as your Tactical layer. You need to upgrade the building of your Base to unlock certain capabilities - for instance, unlocking Medical Wing so you can get the Healing support station to deploy during battle). This will allow you to have better “arsenals” at your disposals. For instance, do check out your Talents, Perks and your Signature Skill by pressing (L)oadout. That Signature Skill is where you can have a Healing Station deploy just beside you to heal you while you faced off… or you can have a Fire Turret to burn the enemies as the come near you and while they are burning, they are vulnerable and you can shoot their heads.
Weapons stability is UTMOST important in early games, imo. You might be a l33t shooter but if you didn’t mod your weapons with Stability mods, you will always miss. Perhaps @malkav11 have also miss out this important thing when he started - I also learned it the hard way and only after learning this tip from a fellow friend (yes, the game doesn’t tell you any of this stuff, so it’s easy to get frustrated).
Don’t spend money buying weapons from the vendors, but instead spend money buying weapon mods and gear mods. Focus on Stability, Chance to Hit and Critical Damage.
Focus on mods that lengthen your turrets or healing station duration so you can last longer. Don’t forget to press G to throw grenades to flank the enemies. And also V to use a medkit to temporary boost your health.
