I tried both gamemodes some minutes ago, I liked both and I found no bugs.
Arsenal
I like this gamemode more than Gun Game because it have all the weapons except explosives. The gamemode is working right, the bots, like in any other mode are just stupid.
I will suggest to change something, though. If you are for example in level 7 and you press "Voodoo" key, I think it should show you the second page first, then the third one and hide (or after the third, show the first and then hide), so you don't have to wait to change the pages and see your next weapon.
Tournament DeathMatch
The problem is that the gamemode uses teamplay spawn points, so even if there's no "enemy radar" (you can only see the team mates), so spawn killing is very easy. Apart of that, the gamemode is good.
Spanish translation
The spanish translation is good now, but in Arsenal, when you press "x" for the gamemode info, in "Press your Voodoo key (G) to print the arsenal" it says (< NOT BOUND >) and not the bind you have.
