Intro/General Tips
Green Team starts near a river. You may need 1-3 bridges built to avoid wading. You sort of blend in with the ground, which helps you to be undetected. The Blue Team will use the rivers in your area to their advantage. Get them before that happens.
The green team has less of an advantage than the blue team. These players generally are defense. On offense, it is best to go in groups above the ground until you reach the mountain with the intel. Then, everyone should dig to breach the enemy base. On a solo approach, try and stay invisible, meaning dont kill or shoot at all, just keep moving. If needed you should attack if they did but I don't recommend this. Then, tunnel to the base and kill them or grab the intel. Its only good to grab the intel if there is an easy escape or if you have others on your team with you.
Green is good at defence. Team build a tower near your intel. Have 1/2 of the team attack the other team's base and the others stay and defend, beacuse blue team is more aggressive. The other team will most likely use the river and there shade to their advantage. It's hard for them to dig under your base but it is still possible.
