So what about the genestealers, will they be in the mod or it's a stopped work, i don't know and when the genestealer gets on, wich one will be the space marine counter?

maybe the ravenor could have a shotting weapon in the down arms like in the table top such as a deathspitter or a devourer

ok if you want more info about my ideas i tell it now.
Ok the heavy bolter theme is not A PRIORITY but by only making the hi-capacity mag will be enough. i think you don¡t need more explanation.

The plasma gun is a lil bit longer.
First of all it sould have a low fire rate but much more damage than the normal bolter, and it doesn't do any splash damage, but it gets overheated and if it's fired to much fast needs a cooldown time of 6 seconds or whatever you think is a good time of cooldown. And the tyranid counter is a Carnifex but with a venom cannon, deathspitter or devourer in the down arms.

And the space marine scout cold be a super cheap unit with a silenced bolt pistol and a sniper riffle hat kills with one or two shoots depending of the enemy who he is facing, he has stealth ability like the liktor and he is much faster than a normal marine but with a very light armour. The tyranid counter could be the Ravener as i told you before but this are only suggestions.

you sould make the chimera's lasscannon longer so it looks like better and it's really easy.

i know this thread was only a list of ideas not ehat you sould do i put this becase i think that this ideas can make the game even better and it's not a priority, of course it's not! but i like giving my ideas and i accept everything you tell me this where only ideas, for first if you think that some of this ideas can be tested or started ok then i gave you everything i thought for them, just if you have a fast look to the S.M. codex you can see many things.

i know that some or all of this ideas can be rejected so i was only making a small contribution.
and i have more ideas if you want just a little bit of orientation of what will the normal half life 2 users think about this mod.

well first of all i don't know if this is where i must put this so admins erase or move it, but read it before please.
I'm new here but i would like to help you with some ideas and i could make some work.
First of all you should put the feeding system of the heavy bolter for the heavy marine, or put the high capacity magazine.

Seond: in th veteran marine you should put the sword more to the center and the gun all to to right so it looks like more realistic.

Third: Make the chimeras bigger and the thunderhawk bigger, but the harpy smaller and put three in the air not one.

Fourth: It would be cool to put a Scout marine with a Snioer riffle and a silenced boltpistol as a playable unit for a special mission or something like that. Also make a unit like the scout but for the tyranids such as a Ravener.

And last of all my ideas is to make the special weapon operator a plasma rifle it will be really cool.

Thanks for reading, keep working on this awesome mod!
