Here are some ideas

-New Class for Aliens: Krell
Basically a flying alien (between maruder and goon) with 125 health. Primary attack would be shooting acid forward. Point would be to counter JetCampers. The acid would look like a fast, small ball and do 3 damage to buildings and 33.4 damage to humans. The Advanced Version could shoot spikes (2) that deal 66.7 damage to humans and 50 damage to buildings and would travel strait as well. If their wings were hit they would fall, like a jetpackker. About the size of a granger.
-New Weapon for Humans: Electric Prod
Basically a long metal pole with two electrodes at the end to shock aliens, basically a longer range and higher damage pain saw. Would deal 50 damage per second and would be about 7.5 feet tall (assumming a human is about 5'10"-6'). Would slow down aliens by 20%.
-New commands
-Admin
-/viewIP [NAME] (View IP of a player)
-/banIP [PLAYER NAME or IP or IP with wildcard] (Ban an IP or an IP range (using wildcards (12.342.682.*)))
-/instantReplay [LOCATION] [TIME] (Instant replay: View what was going on at a location at a specific time (to prove wrongdoing for bans/kicks)))
-Servers
-g_maxStructures [NUMBER] (sets the number of max structures for each team (to prevent lagg)
-Humans only fall if jetpack is hit
-Recoil: after firing a wep, humans get moved back (only on Luci, shotgun, lasgun, pulse rifle and rifle)
-Force Shield (Human Barricade)
-Teslas should go between aliens, like a marauder's zap goes between humans
-You cant die while within 5 feet of spawn for 5 seconds after spawning (to prevent camping)
-Make Granger spit do 10 damage and reduce human speed by 50%
-Add a function to convert the dm_69 format to avi (i know it takes up RAM)
-Add screenshots in formats other then JPEG (bmp, png, gif, tiff, etc)
