This is my favorite CO build, and though sometimes people get angry with me for not going onos/fade, you cant argue with the kills
Its AlmightyNu's Uber Skulk build:
1. Carapace - I get this right off the bat because it can get you time for an extra kill or two before death, and in a game where kills = power, its important to keep the advantage.
2. Celerity - Every second you aren't harassing/killing marines is a second wasted; plus there is nothing worse than being on the verge of killing a high level heavy, or their command chair and dying, and having to take forever getting back to finish it off.
3. Silence - I feel this is underused, especially in public servers. I find that if you can manage to get behind a group of marines, this is 10x better than cloaking; and unless they are experienced players, marines tend to get disoriented and panicky when the people around them start dropping inexplicably.
4. SoF - ...and the best way to get behind those groups of marines is to know where they are. With cloaking you can wait for them to pass, or walk in and get one kill, but for those of us who are impatient to slaughter large groups, SoF + silence is wonderful
5. Regen - With silence and carapace, its likely you might get hit intermittently, but still survive, and the best way to keep the damage from building up is regen
By this time, you should already be able to take out large groups of marines going solo or with another attacker to even increase marine disorientation, everything else is just gravy after this, and the order doesn't matter as much.
6. Adrenaline - When rushing around the feet of marines, or attacking a forgotten command chair, you dont wanna run out of attacks.
7. Unlock: leap - Helps you travel faster, and when chasing a group of marines from behind, is a great way to get off that first attack, plus a silence leap is freaky to marines.
8. Save
9. Unlock: Xeno - lets face it, xeno is incredibly useful in the right situations, especially in large games. Great for following up a fade or onos attack.
10. CloakingWhyNot - By this level the upgrade can't significantly improve you, but there are times when cloaking comes in handy.
The soul of this build is to run up behind large groups of marines, disorient them, and kill them.
There are some tips for alien combat, that this build makes the most of:
There are about 3 main paths between the hive and the marine base, 1 of which is usually neglected, keep this in mind
These paths are
interconnected! Too many aliens and even more marines tend to play by running straight down one path toward the enemy base.
What you should be doing is using SoF to watch for large groups of marines moving towards your base as you run down a
different path, then running in behind them and killing them off (yes even heavy trains can fall to this skulk). They wont expect it, and may not even notice until their health is dropping, when it is too late. The benefits of this is that:
1. It protects hive from organized offensives
2. It gets you lots of kills
3. As it is nearer your base, it gives more kills to your teammates, as you dont need much past level 6 to max out
4. Your versatility also allows you to run around masses of marines to attack the defenseless command chair. Always find the one entrance to the marine base that they dont watch, and come in that way.
Keep in mind that this build works best on public servers against moderately experienced players, keep this in mind before attacking me about how it doesn't work against expert marines.
