For anyone having issues with speed stars wait til you have the 3rd set of leg and pick spider legs, auto-cannon (1st weapon 2nd row), and High caliber cannon (same spot in shoulder). The latter of which pierces through enemies and combined they let you blow up most bosses in 2-3 shots of the cannon.
If you're gonna force us to use a weapon make sure it's not hot garbage like the frozen death. Especially if you're gonna give the human ai the regular rocket launcher which 1 shots you. Mission 14 of alien is the level that earns this game a 1 star.
It's not fun, it's cheaply hard when the two humans have a vastly superior explosive weapon and your two ai buddies just feed kills the entire match. Then when you do well the game gives you a middle finger and has the ai spawn right beside you with their rocket launcher/ion cannon.
Endless mode to 3k feels like it'd take an hour at least and the game isn't interesting enough to do the same 10 patterns over and over especially when it comes down to simply how many times you get the V of cars followed by the full screen bombing because it's guaranteed to hurt if not outright kill some of your squad. For added fun a helicopter can come before the left side is bombed so you have 0 chance to recover.
The clue on 21 makes no god damn sense. First one is NE then second one is W, but third one isn't W or even SW it's SWW. Then it's SEE and finally north the clue's order isn't remotely the same.
For TL:DR just want solution for 21: NE, W, SWW, SEE, N
Ally status requires excessive grinding and equipment has stats on it that are useless to you. Ranger gear should not have strength or focus on it and vice versa for rest of gear.
